Abstract

PURPOSE:To improve a hysteretic characteristic so as to approach a loop type, reinforce the strength of stability and improve earthquake resistance by welding a gypsum plate to the fitting end of a brace and connecting its horizontal part to a beam and its vertical part to a column by means of bolts. CONSTITUTION:A gypsum plate 11 provided with a horizontal part 14 and a vertical part 15 is welded to the fitting end of a brace 13. The horizontal part 14 is connected to a beam 18 by a bolt and the vertical part 15 to a column 17. The horizontal element of the tension stress acted on the brace 13 is imposed on the junction bolt with the column and the vertical element is imposed on the junction bolt with the beam so as not to generate shear load. As a result, a slip type hysteretic characteristic of the brace structure is improved and can be made close to the loop type hysteretic characteristic of a rigid structure.

This does not use a rigid joint between the columns and beams as in a rigid frame, but instead supports the horizontal load with braces that pass the load diagonally. Figure 3 shows the framework of a building with such a brace structure, in which beams (2) (2) are installed between columns (1) (1), and these columns (1) Braces (3) (3) are passed diagonally across the space surrounded by the beam (2) and the beam (2), respectively.

Problems to be Solved by the Invention This type of brace structure has the disadvantage that the hysteresis characteristics when subjected to a horizontal load become a so-called slip type as shown in FIG. 5, which is not very desirable. That is, FIG. 6 shows the hysteresis characteristics in the case of a rigid frame structure. In this case, it has a so-called loop shape, has excellent restorability when deformed by a load, and has good earthquake resistance. It is certain that one of the reasons why the so-called restoring force of the brace structure is not stable is that the brace (3) itself has no restoring force when its composition is deformed. When the joint method in 3) is a bolt joint, the joint has a structure that produces a shearing force on the bolt (4) as shown in Figure 4, and the shearing load causes this fourth Bolt holes (

Means for Solving the Problems And in order to achieve the above object, in this invention, the brace is attached by welding a joining plate having a horizontal part and a vertical part at the end, and bolting the horizontal part to the beam. , the vertical part is attached to the column by bolting.

The horizontal component of the tensile stress on the brace is borne by the horizontal bolts, that is, the bolts that connect it to the column, while the vertical component is borne by the bolts on the beam side, so it does not become a shear load and is supported by tension. Therefore, it is possible to improve the history characteristics.
