要旨 Xiaoyudong Bridge, a rigid-frame arch bridge, received great damage in Wenchuan Earthquake, 2008. Based on the detailed field survey, failures of Span 1 were mainly caused by the surface fault, while Span 3 and 4 entirely collapsed, and Pier 3 titled about 7.5° mainly by the seismic effect. Pushover analyses were performed to evaluate the bearing capacity, and to approach the mechanisms of Span 4. Consequently, the reinforcement of mid-span may firstly yield at 0.40g. However, the support loss will cause failures occur earlier, which is considered to be the main reason of the collapse of Span
