Spatial seismic response analysis of self-anchored suspension bridges subjected to multiple-support excitations

Based on random vibration theory, by taking into account the seismic action with spatial variation, the earthquake response of a self-anchored suspension bridge with center span of 240m to multiple-support excitations is investigated, and numerical calculation is presented for seismic response subjected to independent effect or combination effect of three orthogonal components of seismic wave. The seismic response of self-anchored suspension bridge by considering traveling effect and correlated effect is discussed in detail.
