A comparative study of selected bridge damage due to the Wenchuan,Northridge,Loma Prieta and San Fernando earthquakes is described in this paper.Typical ground motion effects considered include large ground fault displacement,liquefaction,landslide,and strong ground shaking.Issues related to falling spans,inadequate detailing for structural ductility and complex bridge confi gurations are discussed within the context of the recent seismic design codes of China and the US.A signifi cant lesson learned from the Great Wenchuan earthquake,far beyond the opportunities to improve the seismic design provisions for bridges,is articulated.
