Abstract: Based on random vibration theory, by taking into account the seismic action with spatial variation, the earthquake respons of a self-anchored suspension bridge with center span of 240m to multiple-support excitation is investigated, and numerical calculation is presented for seismic response of self-anchored suspension bridge by considering traveling effect and correctated effect is discussed in detail.
Key words: multiple-support excitations; self-anchored suspension bridge; earthquake reponse
