EQUIVALENT STATIC LOADS FOR NONLINER SEISMIC DESIGN OF SPATIAL STRUCTURES

摘要：

A new approach to determination of equivalent static seismic loads is presented for evaluating peak seismic responses. The responses are estimated by series of multi-modal pushover analysis considering possible phase differences in the dominant modes: the loads are directly applied in the elastic systems, and the damping due to plastic dissipation is modeled by equivalent linearization in inelastic systems. The accuracy of the proposed method is demonstrated in the numerical example of an arch-type long-span truss.
