This steel plate earthquake-resistant wall is incorporated into a frame mainly composed of steel columns and beams by high-strength bolts or welded joints.

構造を提供する点にある。The conventional steel plate shear wall is intended to exhibit a large external force, mainly stable during a large earthquake, and to exhibit a large plastic energy. Therefore, during relatively small and medium-scale earthquakes that occur relatively frequently, the shear walls are designed to stay within the elastic range. The present invention is proposed in view of the above problems, and its object is to exhibit plastic strain energy even during frequent small and medium-scale earthquakes, reduce horizontal vibration of buildings, and improve livability. Another object of the present invention is to provide a steel plate wall structure for a vibration control framing structure, which is capable of exhibiting high plastic strain energy even during a large earthquake.

And the combined steel has already exhibited plastic strain energy,
Has energy absorption performance. Immediately after the ordinary steel p has yielded, the combined steel of the extremely low yield point steel q and the high tensile tension steel r has a higher energy absorption performance of the ordinary steel p than the above-mentioned combined steel, but the deformation (strain) is large. Then, the difference between them almost disappears, and in the event of a large earthquake, the same level of seismic performance as conventional seismic elements can be expected.

Is a steel column, 2 is a steel beam, 3 is an orthogonal beam, 4 is an extremely low yield point steel wall panel, and 5 is a high tensile strength steel wall panel. (1) A wall panel is formed by alternately arranging ultra-low yield point steel wall panels 4 having a yield point of about 1.0 t / cm 2 and high-strength steel wall panels 5 in the columns 1 and the beams 2. (2) At the time of a small-to-medium-sized earthquake, the ultra-low yield point steel wall panel 4 is plasticized, while the high-strength panel 5 is kept in the elastic region. (3) In the event of a large earthquake, the extremely low yield point steel wall panel 4 and the high-strength panel 5 are plasticized. Since the extremely low yield point steel panel 4 may yield at an early stage due to repeated stress and cause fatigue failure, it is detachably joined with high-strength bolts 6 so that it can be replaced in the event of a failure. ing. The high-strength steel wall panel 5 is provided with a stiffener 7 which prevents the high-tensile steel wall panel 5 and the entire wall plate from shearing buckling, and when the extremely low yield point steel panel 4 yields. Exhibits a stiffening effect.
