Abstract
This new versatile steel connection has three unique features: (1) utilizes three dimensional connection plates in a simple and consistent manner, and is suitable for all possible connection type that is made of steel W-sections; (2) uses through the depth steel rods, coupled with typical web stiffeners to transfer shear and bending moment across the connection. The shear transfer mechanism is similar to stirrups in reinforced concrete beams; (3) all components and parts can be prefabricated in shop, and conveniently bolted together at field. The merits of the connections include higher strength and ductility, stronger yet simpler connections, higher quality, small components for easy storage and transportation. In one word, it eliminates all of the inherent drawbacks and problems of conventional bolted and/or welded connections.
Description
Bolted Steel Connections with 3-D Jacket plates and Tension Rods Technical Field The invention is directed to structural steel connections, building frames incorporating said connections, and steel trusses incorporating said connections.
Background A completely new type of structural steel connection is invented. It is the jacket-plate-connection system using 3-dimensional connection plates and tension rods to achieve exceptional structural performance that is superior to any conventional connections, either bolted or welded, that use 2-dimensial (i.e. flat) gusset plate and/or side plates. The merits of the novel connections include higher strength and ductility, stronger yet simpler connections, higher quality, small components for easy storage and transportation.
Additionally, they eliminate all of the inherent drawbacks and problems of conventional bolted and/or welded connections. The present invention is a versatile connections system that can be use in any steel frames and trusses that is made of W-sections. It basically redefines concept of structural steel connections, and has the potential to reform the current market of steel construction. The economical and social impact will be significant.
Summary of the Invention In one embodiment, the invention is directed to a steel connection. The connection comprises: a pair of symmetrical jacket plates comprising: a flat side plate that cut into the shape of the side projection of a joint; and pairs of clamping plates welded at the perimeter of the side plate with pre-drilled bolt holes, wherein the clamping plates are perpendicular to the side plate. The steel connection is formed from the pair of symmetrical jacket plates, installed from an opposite side of a frame or truss, and shear transferring threaded tension rods with bolts at each end, or conventional bolts, coupled with typical web stiffeners.
The tension rods or bolts are inserted through the pre-drilled bolt holes of each of a pair of clamping plates, in a plane parallel to the side plate. The tension rods extend the full depth of the frame or truss from clamping plate-to-clamping plate.
The connection may be used in a number of building frames, including: ordinary moment frames (OMF); special moment frames (SMF); eccentrically braced frames (EBF);
ordinary concentrically braced frames (OCBF); special concentrically braced frames (SCBF), including but not limited to, inverted V type, X type, and any typical type;
or another steel frame that is a combination of the above listed frames.
The connection may also be used in a number of steel trusses, including:
Vierendeel trusses; typical steel bridge trusses; a steel truss - N brace; or another steel truss that is a combination of the above listed trusses.

There are three very unique features of this connection system: (1) For the first time in the industry, this invention introduces three dimensional connection plates in a systematical way. It addresses all possible connection type in a simple and consistent manner. (2) This invention uses through the depth steel rods, coupled with typical web stiffeners to transfer shear and bending moment across the connection. This type of shear transfer mechanism is similar to stirrups in reinforced concrete beams and columns. Although being widely used in reinforced concrete structures for many years, it is first time that the mechanism being ever utilized in steel frames and trusses; (3) all components and parts can be prefabricated in shop, and conveniently bolted together at field. With this invention, it becomes practical to build all steel frames without field welding, including the following popular high performance seismic steel frames: special moment resisting frame (SMRF), eccentrically braced frame (EBF), and special concentrically braced frames (SCBF). (Note that there are no all-bolted SMRF, EBF and SCBR at the current market, due to the fact that traditional bolted connections cannot achieve the required strengthen and ductility at practical costs. In other words, these connections are all or partially welded connections.)
