The seismic spatial effect is important for long span spatial structures. The multi-support seismic excitation should be considered. As a case for study, the seismic analysis of Jiangnan University new stadium dome under multi-support seismic excitation is performed. The OPENSees analysis program is used to perform the nonlinear time-history analysis. In the finite element analysis, the fiber section fiber beam element is used to model the nonlinear behavior of steel tube member under seismic excitation. The structure dynamical response under both the consistent seismic excitation and the multi-support seismic excitation is analyzed using different seismic time-history record. The numerical analysis result shows that the steel dome dynamic response under multi-support seismic excitation is different from that under consistent seismic excitation. The influence of the traveling wave and the multi-support excitation on the steel dome response is analyzed. The analysis result gives more guidance on the stadium dome aseismic assessment.
