| 抄録（英）： |
Reinforced concrete buildings with a soft first story subjected to horizontal and vertical motions were simplified as one-mass and two-degree-of-freedom systems, and the effects of vertical motions on the response and collapse behaviors were discussed. δ-P effect and deterioration of materials were considered. Elasto-plastic response analysis concluded that the level of input earthquake and the maximum horizontal displacement at collapse of the buildings will be significantly decreased if the vertical motions were also inputted, as the axial deformation of columns will be increased and accumulated. Correspondence between vertical potential energy and vertical input PGV was found, and a simple prediction formula was proposed for evaluation of building collapse.
