Equations for evaluating the time history responses of the story shear and story drift of multi-story regular-shaped buildings had been proposed by one of the authors. The applicability of the proposed equations to multi-story irregular-shaped buildings consisting of mixed soft and rigid stories in which the story collapse mechanism is formed under earthquake motions was investigated in this study. This paper shows that the equation for the story shear response is applicable to the irregular-shaped buildings. On the other hand, the prediction accuracy of the story drift response by the proposed equation for the irregular-shaped buildings is less than that for the regular-shaped buildings, because the variation of higher vibration modes in the irregular-shaped buildings is larger than that in the regular-shaped buildings. Then, an equation for evaluating the time history responses of the story drift considering the effect of the variation of higher vibration modes is proposed.
