RC下階壁抜け柱における地震時の圧縮軸力の検討

抄録

When seismic force acts on the RC frames, the axial compressive force acting on a column supporting the wall above at the soft story where the wall panel is removed, is increased by the movement of the wall. As the method of estimation performed now of the axial force is for the case the whole panel is removed, there are problems in cases in which the wall has an opening in the side of the column. We investigate those cases comparing the results of the method and of FEM calculation.
