The seismic performance of urban viaduct was studied by considering the Yihe Road viaduct bridge as a case,with a compre-hensive consideration of structural safety and economy.Spatial models for different span combinations,support types,and seismic sys-tems were established using finite element software for seismic analysis.The results demonstrated that the design approach of setting double fixed supports at the middle pier for a span combination of three 30 meter standard spans and setting friction pendulum supports for large span continuous beams with a middle span of 66 meters effectively meet the structural safety requirements under seismic con-ditions.
