を示し、全体として点線Ｅで示すような理想的特
性に近づけることができる。 Next, the operation of the device of the present invention constructed as described above will be explained. When a large horizontal force is applied to a building due to a major earthquake or the like, the horizontal force acts on the joint between the load-bearing wall 3 and the steel frame 1 because the load-bearing wall 3 has high rigidity. That is, in FIGS. 1 and 2, when an external force is applied to the web 4a of the T-shaped steel 4 via the steel plate 5 and the connecting plate 6, the flange 4 of the T-shaped steel 4
Although both ends of the flange 4b are supported, the middle part of the flange 4b from which the web 4a protrudes is in a free state, so if an external force exceeding a set value is applied to the web 4a, the middle part of the flange 4b will be deformed. and absorb some of that external force. Therefore, according to the device of the present invention, until the T-shaped steel 4 is deformed, it exhibits the same characteristics as a conventional rigid structure building as shown by the curve C in FIG. 7, and after the T-shaped steel 4 is deformed, As shown by curve D, it exhibits characteristics similar to those of a conventional flexible structure building, and as a whole can approach ideal characteristics as shown by dotted line E.
このため本考案装置によれば、大地震に遭遇し
ても耐力壁や鉄骨フレームが破壊したり、損傷を
うけることなく、Ｔ型鋼のみの変形によつて地震
による入力を吸収することができる。 Therefore, according to the device of the present invention, even if a large earthquake occurs, the load-bearing wall or steel frame will not be destroyed or damaged, and the input from the earthquake can be absorbed by deforming only the T-shaped steel.
