Abstract

PROBLEM TO BE SOLVED: To form the connecting section of a column and a beam in pin- connection, and to shorten the buckling length of the column. SOLUTION: The intermediate section of the column and the intermediate section of the beam are connected by knee braces 18 in the vicinity of the connecting section 16 of the column 11 and beam 12 of the building in an attic space 15, and the connection structure is formed in rigid joint by the connecting section of the column and the beam and the whole sections joined by these column and beam and the knee braces. Accordingly, the connecting section of the column and the beam can be formed in pin-connection, and the buckling length of the column can be shortened. When at least a part of a plurality of the knee braces is made of dead soft steel, a simple vibration control frame at a low cost is enabled as the buckling length of the column 11 is left as it is shortened.

2. Description of the Related Art FIG. 1 shows an example of a connection structure between a pillar and a beam of a building such as a research laboratory or an IC factory, which is generally known in the prior art. In the figure, reference numeral 1 denotes a column, 2 denotes a beam, 3 denotes a ceiling, and 4 denotes a slab. In this type of building, a large space is formed in a ceiling space 5 surrounded by a ceiling 3 and a slab 4. This is because a large-diameter duct is housed in the space above the ceiling in order to supply a large amount of clean air to the indoor side, and to discharge air contaminated in the room to the outside.

However, the conventional structure for connecting columns and beams of a building as described above has the following problems.
That is, in the case of a building having a long span, a truss structure beam 2 may be used, but in the case of a building having a short span, it is general that the column 1 and the beam 2 have a single-frame structure. . In this case, since the connection portion between the column 1 and the beam 2 has a butted structure, the structure itself is complicated, and the construction is troublesome. In addition, the buckling length of the column becomes longer and the strength is inferior to that, and there is a problem that the diameter of the column becomes larger to make up for it. In addition, since the height to the beam is high, there has been a problem that interlayer deformation is increased.

The connecting portion 16 between the column 11 and the beam 12 is connected by a pin using, for example, a gusset 17 or the like. That is, for example, a gusset is fixed to a pillar by welding or the like, a beam is overlapped on the gusset, and a pin is connected by bolt connection. Further, an intermediate portion near the connecting portion 16 between the column 11 and the beam 12 and below the connecting portion 16 of the column 11 and an intermediate portion closer to the center of the beam than the connecting portion 16 of the beam 12 are closer to each other. Are connected by a forehead 18. The connection method between the stake 18 and the intermediate portion of the column 11 or the intermediate portion of the beam 12 is, for example, a rigid joint in which a joining plate is extended from the column 11 or the like and the end of the sway is welded thereto, It may be a pin joint for connecting the beam 12 to a joint plate extending from the column 11 or the like by a bolt or the like. In short, pillars 11 and beams 12
It suffices if the middle part of is connected. Further, the guide 18 is housed in the space under the ceiling 15 so as not to be exposed downward from the ceiling 13.

Further, there are a plurality of the guides 18 corresponding to the number of the beams 12, at least a part of which is made of extremely mild steel,
For example, it is made of extremely low yield point steel made of steel having an extremely low yield point. It is needless to say that all of the plurality of members 18 may be made of extremely mild steel, and one of them may be made of extremely mild steel. In short, the number and position of the ultra-mild steel slabs may be determined from the balance between the vibration damping action of the ultra-mild steel and the strength as the slab.

According to the connection structure between the pillar and the beam of the building having the above-described structure, the pillar 11 and the beam 12 are directly pin-connected by using a gusset or the like, and the intermediate portion of the pillar 11 and the beam 12 are connected. Since the intermediate portion is connected by the guide 18, the column 11 and the beam 12 are rigidly joined when viewed from the entire joint. In other words, the bending stress between the column 11 and the beam 12 is obtained by the orientation 18, so that it is sufficient for the direct connection portion 16 between the column 11 and the beam 12 to be pin-coupled. For this reason, the structure of the direct connecting portion 16 between the column 11 and the beam 12 can be simplified. As shown in FIG. 2, the buckling length L of the column 11 is from the lower end of the guide 18 to the FL, which is much shorter than that of the related art. For this reason, a great increase in strength can be expected, and in order to obtain the same level of strength as before, the column diameter can be reduced.
