概要 In this present article, shaking table tests of multi-story irregular building models are carried out, and the influence of the direction of incidence of seismic input to the response of irregular building is investigated. The results show that the influence of the direction of seismic input to the magnitude of the peak base torque is quite significant; there exists the critical direction of seismic input which produces the largest base torque. The modal decomposition of each test result also reveals that the direction of incidence of which the largest torque occurs is close to the direction that the largest first modal response occurs. Based on these results, it is concluded that the critical direction of each building models is roughly coincide with the principal direction of the first modal response proposed previously by the author.
