Definitions

  • the present invention generally relates to moment resisting, bi-axial beam-to-column joint connections, and more particularly to a gusset plate assembly used with a hollow tubular column for a bi-axial beam-to-column moment-resisting joint connection.
  • US 3,914,063 describes fixtures in the form of an assembly including a base plate and a pair of intersecting vertical plates fitted together and in mating recesses in the base plate.
  • the fixture assemblies are provided with welds along the intersecting seams formed between the vertical plates and the base plate.
  • Hollow tubular columns are structurally efficient members to use in a variety of building design applications (both structural and architectural), including moment frames.
  • Hollow tubular columns include, but are not limited to, Hollow Structural Section (HSS) columns and built-up box columns.
  • HSS Hollow Structural Section
  • traditional moment connections types that connect a wide flange ('H' section) beam to a hollow tubular column involve significantly different design considerations than does connecting a wide flange beam to a wide flange column.
  • the moments in the wide flange beams are resolved into concentrated forces at the beam flanges that must be transferred into the column.
  • the main difference between a hollow tubular column and a wide flange column is how the forces from the beam flanges are transferred into the column webs to be resisted as shear.
  • the web In a wide flange column, the web is located at the center of the column flange.
  • the forces from the beam flanges applied to the column face must be transferred to the sidewalls of the column, which act as the webs of the column.
  • the side walls of the hollow tubular column facing the beams "flange walls" must structurally span between the other sidewalls ("webs") of the column to transfer out-of-plane forces from the beam flanges to the column webs. Accordingly, for such traditional moment connection types, the thickness of the flange walls of the hollow tubular column becomes a critical consideration for the out of plane strength and stiffness of the flange walls.
  • connection Another conventional method is through-plate connections wherein the hollow tubular column is cut in two places at each floor level to allow through-plates attached to the top and bottom flanges of the wide flange beam to pass through the column.
  • These through-plates are welded along the full perimeter of the cut sections of the hollow tubular column on both top and bottom faces of each through-plate.
  • These type of connections have proven to be both costly to fabricate and uncertain in their performance when subjected to violent earthquakes.
  • the connection may be inherently susceptible to out-of-plane punching shear failures in the through-plate due to cyclic tensile forces in the column.
  • Exterior diaphragm plate connections are similar to the through-plate connections in that they use flange plates attached to the top and bottom flanges of the beam to transfer the moments.
  • the hollow tubular column remains continuous and the top and bottom flange plates are made wider than the width of the hollow tubular column to allow for cut openings having a perimeter that surrounds and is attached to the full perimeter of the hollow tubular column. This connection is inherently difficult to fabricate and erect.
  • Interior diaphragm plate connections consist of shop welded plates that are cut to fit along the inside perimeter of the hollow tubular column, thereby stiffening the flange walls of the hollow tubular column and thus providing a strengthening means to transfer beam flange forces to the sidewall webs of the hollow tubular column.
  • Top and bottom flanges of wide flange beam are directly welded to the flange wall faces of the column.
  • the fabrication of this connection type is difficult because of precise fit up issues and difficulty in access for welding of interior diaphragm plates to inside faces of the hollow tubular column.
  • the performance of this connection type is correspondingly uncertain.
  • a gusset plate assembly for use in connecting at least two beams to a hollow tubular column in a building is configured to receive said at least two beams in a biaxial orientation of said beams.
  • the gusset plate assembly generally comprises gusset plates sized for transferring the weights of said at least two beams and their reaction forces and bending moments from the application of severe load conditions acting on the building to the hollow tubular column.
  • At least a first of the gusset plates is configured to receive a portion of a second of the gusset plates therein.
  • a joint penetration groove weld joins the first and second gusset plates together.
  • a method of constructing a gusset plate assembly for use with a column assembly including a hollow tubular column and connected gusset plates configured to form bi-axial moment connections with beams in a building framework comprises mating a first of the gusset plates with a second of the gusset plates so that a portion of at least one of the first and second gusset plates is received in an open slot of the other of the first and second gusset plates whereby inner surfaces of the mated gusset plates define an interior corner and outer surfaces of the mated gusset plates define plural exterior corners.
  • a joint penetration groove weld is formed on at least one of the exterior corners of the mated first and second gusset plates.
  • a bi-axial beam-to-column moment-resisting joint connection structure including a column assembly is generally indicated at 11.
  • the joint connection structure may be used in the construction of a building framework 1 (see, Fig. 1 ).
  • the joint connection structure joins a column assembly 13 including a column 15 to a plurality of full-length beam assemblies 17 each including a full-length beam 19.
  • a full-length beam is a beam that has a length sufficient to extend substantially the full-length between adjacent columns in a structure.
  • a stub and link beam assembly as shown in Figs. 5 and 16 of U.S. Patent No. 6,138,427 , herein incorporated by reference, is not a full-length beam.
  • the present invention may be used with stub and link beams and other beams that are not full-length beams.
  • the beams 19 in Fig. 2 have been broken away, but are full-length beams.
  • the beams 19 may have any suitable configuration, such as an I-beam, H-beam configuration, or hollow rectangular shape (built-up box member or HSS tube section).
  • the joint connection structure has a 4-sided/4-beam configuration whereby four full-length beam assemblies 17 are configured to be attached to the column assembly 13.
  • other joint connections 11', 11" using column assemblies 13', 13' involving three beams and two beams are also employed in the framework 1.
  • the construction of the beam assembly 13', 13" may be closely similar to what is described for column assembly 13. It will be understood that some of the column assemblies 13, 13', 13" in the framework may have a construction different than that described for column assembly 13 herein.
  • column 15 is an HSS tube section structure having a rectangular (broadly, "polygonal") cross section defined by four column faces 20A, 20B, 20C and 20D.
  • the column 15 may have other configurations, such as a built-up box member, and in general will be referred to as a hollow tubular column.
  • the column 15 comprises an enclosed rectangular wall including opposing planar wall members.
  • the global moment-resisting frame design configuration of the building framework 1 can, as needed, provide a distributed moment-resisting space frame wherein all or most beam-to-column connections are moment-resisting in each principal direction of the building.
  • This bi-axial beam-to-column moment resisting framework 1 is in contrast to conventional building frameworks which may use fewer discretely located uniaxial moment frames throughout a building foot print in each principal direction of the building.
  • the global frame structure that is framework 1 is a beam-to-column framing system that maximizes structural redundancy in the lateral load resisting system of a multi-story building to increase resistance to progressive collapse scenarios when subjected to, for example, terrorist bomb blast and other catastrophic load environments. Other configurations are possible.
  • another cost-effective framework constructed according to the principles of this invention can include fewer but discretely located biaxial moment resisting joint connections.
  • Such a framework can achieve similar performance objectives while minimizing the number of required moment-resisting beam-to-column joints to be constructed, which in turn reduces construction costs.
  • the column assembly 13 includes a collar like gusset plate assembly 21 for attaching the column assembly to the beam assemblies 17, similar to what is shown in co-assigned U.S. Patent Application Serial No. 15/144,414, filed May 2, 2016 .
  • a unique method of fabricating the column assembly 13 using the column 15 as a jig for building up the gusset plate assembly 21 in an ordered sequence, one gusset plate at a time, will be described in more detail hereinafter.
  • the gusset plate assembly 21 comprises a plurality of gusset plates 23A, 23B, 23C and 23D connected to the column 15 and extending laterally outward from the column.
  • the gusset plates 23A-23D extend within planes generally parallel to a longitudinal axis of the column 15, and include bolt holes 26A for receiving bolts 26 to connect the full-length beam assemblies 17 to the column assembly 13 ( Fig. 2 ).
  • a first pair of spaced apart parallel, vertically and horizontally extending gusset plates 23A, 23D sandwich the column 15 and co-axially extending beams 19.
  • the first pair of gusset plates 23A, 23D extends laterally outward from the column 15 in opposite directions along a first column axis and defines spaces for receiving end portions of beams 19 for mounting respective beam assemblies 17 to the column assembly 13 via the gusset plate assembly 21.
  • a second pair of spaced apart parallel, vertically and horizontally extending gusset plates 23B, 23C sandwich the column 15 and co-axially extending beams 19.
  • the second pair of gusset plates 23B, 23C extends laterally outward from the column 15 in opposite directions along a second column axis extending orthogonally to the first axis.
  • the second pair of gusset plates 23B, 23C defines spaces for receiving end portions of beams 19 for mounting respective beam assemblies 17 to the column assembly 13 via the gusset plate assembly 21.
  • the first and second pairs of gusset plates each intersect a single plane perpendicular to the longitudinal axis of the column 15.
  • the gusset plate assembly 21 is constructed and arranged so that four, co-planar beams 19 are connected to the column 15.
  • the gusset plates 23A, 23D have the same construction in the illustrated embodiment.
  • Figure 4 shows one gusset plate, but is designated by both 23A and 23D to indicate that the construction is the same for both.
  • the first gusset plate 23A is shown as it would appear when looking toward a face 20A of the column 15
  • fourth gusset plate 23D is shown as it would appear when looking toward the face 20C of the column.
  • the gusset plate 23A, 23D is shown to include a closed interior aperture 41 (broadly, "elongate opening") having an edge defining a closed loop encompassing the aperture.
  • the gusset plate 23A, 23D also has a pair of open slots 43 flanking the interior aperture 41.
  • the open slots 43 extend from a top of the gusset plate 23A, 23D, where they open upwardly from the gusset plates, to an interior of the gusset plates.
  • One edge margin of the gusset plate 23A, 23D defining an edge of the open slot 43 forms a bevel 44 that facilitates welding as will be described hereinafter.
  • the open slots 43 extend about half the depth of the gusset plate 23A, 23D.
  • the gusset plates 23B, 23C have the same construction as each other but differ from gusset plates 23A, 23D on account of the different orientation these plates will assume in the gusset plate assembly 21.
  • Figure 5 shows one gusset plate, but is designated by both 23B and 23C to indicate that the construction is the same.
  • second gusset plate 23B is seen as it would appear looking toward the face 20D of the column
  • third gusset plate 23C is seen as it would appear looking toward the face 20B of the column.
  • the gusset plate 23B, 23C includes a closed interior aperture 45 (broadly, "elongate opening") of substantially the same construction as the aperture 41, and a pair of open slots 47 flanking the interior aperture.
  • the open slots 47 extend from a bottom of the gusset plates 23B, 23C, where they open downwardly from the gusset plates, to an interior of the gusset plates.
  • each open slot 47 defining an edge of the slot forms a bevel 48 that facilitates welding between mated gusset plates as will be described more fully.
  • the open slots 43, 47 of the gusset plates 23A, 23D and 23B, 23C allow the gusset plates to be assembled with each other and onto the column 15 in an ordered sequential manner, gusset plate by gusset plate, as will be described hereinafter.
  • horizontal cover plates 27 are disposed on top of and attached to an end of the beams 19.
  • the cover plates 27 have a width that is greater than a width of the respective beam 19 and a horizontal spacing between the associated gusset plate pair 23A, 23D and between associated gusset plate pair 23B, 23C.
  • the configuration of the cover plates 27 allows the full-length beams 19 to be lowered between the gusset plates 23B, 23C of respective column assemblies 13 so that each end of the full-length beam assembly 17 is initially supported in bearing between the cover plate 27 and the top edge of the horizontal extension of the gusset plates 23 of the column assembly 13.
  • the beams 19 are self-shoring.
  • the cover plates 27 may rest on a top face of a projecting horizontal leg of upper angle irons 35 attached in a suitable manner such as by welding to the exterior faces of gusset plates 23A-23D.
  • the cover plates 27 extend along the length of their respective beams 19 and terminate at or just beyond the ends of the gusset plates 23A-23D.
  • the cover plates 27 each have an oblong radiused slot opening 30 extending along the length of the cover plate and opening at one edge of the cover plate.
  • U-shaped fillet welds 31 in the slot openings 30 connect the cover plates 27 to the upper flanges of the beams 19.
  • cover plates 27 may have other widths, configurations and slot-type oblong openings.
  • a cover plate (not shown) may have no slot opening 30 or a fully enclosed slot opening.
  • Vertical shear plates 32 (only two of which are shown) are attached in a suitable manner such as by fillet welds 33 to the web of the beam 19 on both sides of the web.
  • the beam assembly 17 is attached by bolts 26 to the column assembly 13 ( Fig. 2 ). More particularly, bolts 26 are received through holes 26A in the cover plates 27 and aligned bolt holes 26A in the upper angle irons 35. Lower angle irons 34 welded to the lower flange of the beam 19 receive bolts 26 that also pass through holes 26a in the gusset plates 23A-23D. In addition, bolts 26 are received through holes 26A in the gusset plates 23A-23D and through holes 26A in the vertical shear plate element 32 for transferring beam shear to the resisting gusset plate 23A-23D.
  • the vertical shear plate element 32 has a suitable configuration, such as that of a vertically oriented angle iron.

  • the beam assembly With the cover plate on the bottom of the beam, the beam assembly can be field erected by raising it so that ends of the beam assemblies are received between corresponding pairs of gusset plates. This is the opposite of what is illustrated in Fig. 1A , where the beam assembly 17 is lowered into place between the gusset plates 23A, 23B of the column assemblies 13.

  • the structure 11 provides for a full-length beam assembly connection along four sides of hollow tubular column 15.
  • Each of the components of the joint connection structure 11, as well as the beam 19 and column 15, are preferably made of structural steel.
  • Some of the components of the joint connection structure 11 are united by welding and some by bolting. All of the welding may be performed at a fabrication shop. The bolting may all be performed at the construction site, which is the preferred option in many regions of the world.

  • the column assembly 13 may be fabricated at a fabrication shop and later transported to the construction site. Formation of the gusset plate assembly 21 can be efficiently carried out using the column 15 as a jig, and with all welds made in the horizontal welding position.
  • the horizontal welding position is the preferred welding position over other possible welding positions such as vertical and overhead welding positions, because of its ease of weld metal deposition, and because of its inherent high level of weld quality and certainty. However, some or all of the welding could be done in lesser preferred welding positions within the scope of this invention. In some instances welding in a flat welding position may be employed. This desirable welding position could present certain challenges in handling the column and jigging the gusset plates, but could be used.

  • the finished column assembly 13 can be transported to the worksite where it can be erected as part of the building framework 1 ( Fig. 1 ).
  • the joint connection structure 11 formed using the column assembly 13 connects four beams.
  • other column assemblies may be formed that may interconnect a greater or lesser number of incoming beams.
  • joint connection structures 11', 11" in Fig. 1 are constructed for receiving three beams and two beams, respectively.
  • Column assemblies 13', 13" of these joint connection structures 11', 11" may be formed using the method of the present invention.
  • the column assembly 13 beneficially distributes the resistance to moments applied by the beams 19 to the column 15 to all four faces 20A-20D of the column, making it well-suited to resist bi-axial loads applied by the beams to the column, particularly in severe load events. This is made possible by the use of welded interlocked orthogonal gusset plates forming the rigid gusset plate assembly 21 that hugs the sidewalls and snugly encloses the corners of the column 15. It will be understood that a moment applied by any one or any combination of the four beams will be transmitted by the rigid gusset plate assembly 21 to locations all around the column 15.
  • connection to the parallel faces 20A, 20C of the column 15 provides a force couple (principally acting in shear along the length of the welds) formed by the top and bottom horizontal welds 53A, 53B, 75A, 75B (comprising a horizontal weld group) connecting the gusset plates 23A, 23D to their respective faces 20A, 20C of column 15 to resist applied moment.
  • top and bottom horizontal welds 83A, 83B of the gusset plate 23B facing the end of the beam 19 comprise another horizontal weld group forming a resisting tension/compression force couple acting perpendicular to the face 20A of the column 15 to resist applied moment.
  • the rigid gusset plate assembly 21 also transmits the moment to the opposite face 20B of the column 15 through its connection to the gusset plate 23C, by providing a redundant resisting tension/compression force couple (acting perpendicular to the opposite face 20C) formed by the top and bottom horizontal welds 67A, 67B (comprising yet another horizontal weld group) connecting the far gusset plate 23C to the opposite face 20B to resist the applied moment.
  • the column assembly is configured to provide further moment resistance unique to bi-axial moments. It can be understood that if moments are being applied to the joint column assembly 13 from beams 19 which are orthogonally arranged with respect to each other, the resolved moment vector would not lie in a vertical plane including the longitudinal axis of either beam. Instead, the moment vector would lie in a vertical plane somewhere in between orthogonal beams 19, and would therefore urge the gusset plate assembly 21 to tilt on the column along a diagonal between the longitudinal axes of said orthogonal beams 19. In this case, adjacent, near orthogonal faces 20A, 20D of the column 15 provide cooperative moment resistance.
  • the welds e.g., welds 51, 68
  • the welds in the vertical apertures 41, 45 in the gusset plates 23A-23D which are centered at the mid-depth of the column 15 on the adjacent faces 20A, 20D orthogonal to each other, provide additional moment-resisting capacity by coupling the same vertical slot welds located in their respective apertures 41, 45, which act together orthogonally as a vertical weld group to provide a force couple to resist the applied bi-axial moment.
  • the rigid gusset plate assembly 21 also transfers the bi-axial moments to the far orthogonal faces 20B, 23C of the column 15, which comprises another vertical weld group to provide additional cooperative moment resistance.
  • Both the near orthogonal faces 20A, 20D and far orthogonal faces 20B, 20C act in concert with the moment resistance force couples described in the preceding paragraph to make the column assemblies 13 and joint connection structures 11 formed using the column assemblies remarkably robust and redundant.
  • load transfer redundancy can also be provided under severe load conditions by a 'push/pull' effect of opposite gusset plates 23 (facing perpendicular to the longitudinal axis of the beam) bearing against the same opposite faces 20 of the column 15 under the applied moment.
  • opposing faces 20 of the column 15 cooperate to resist moment (under extreme load conditions) from one beam 19, in addition to resistance provided by the welded connection of the gusset plates 23 to the orthogonal side faces 20 of the column 15, thereby providing redundancy in resisting applied moment.
  • the column assembly 13 is configured to resist applied moment in the way just described for moment applied for only one beam 19, for as many as all the four beams 19 in the joint connection structure 11 made possible by bi-axial interaction of all aforementioned load transfer mechanisms.
  • the all field-bolted joint connection structure 11 preserves the physical separation (or gap) between the end of a full-length beam 19 and the face of the column 15 made possible by the use of vertically and horizontally extended parallel gusset plates 23A, 23D or 23B, 23C that sandwich the column and the beam similar to prior designs which feature an all field fillet-welded joint connection structure; thus reducing the uncertainty of bending moment load transfer between a rigidly attached steel moment frame beam and column used in the past.
  • this current bi-axial application of an all field-bolted joint connection structure 11 preserves the advantage of increased beam-to-column joint stiffness. There is also a corresponding increase in overall steel moment frame stiffness, which allows smaller beam sizes when the building design is controlled by lateral story drift (not member strength), and hence reduced material costs.
  • this bi-axial all field-bolted joint connection structure 11 When the building design is controlled by member strength (not lateral story drift), this bi-axial all field-bolted joint connection structure 11 also reduces the beam size and the column size, and hence material quantities and cost, because its connection geometry has no net section reduction in either the beam 19 or the column 15 (i.e., no bolt holes through either the beam or sidewalls of the column), thereby maintaining the full strength of the beam and column.
  • full-length beams are connected to gusset plates by bolts so that the full-length beam and gusset plates are substantially free of welded connection. It will be understood that field welding the full-length beam assemblies 17 to the column assembly 13 is within the scope of that aspect of the disclosure, as is providing an all-bearing moment resisting joint connection between full-length beam assemblies 17 and the column assembly 13 (corresponding to the joint connection shown in Fig. 140 of co-assigned U.S. application No. 14/729,937 ).
