Damage of Bridges in 2008 Wenchuan China Earthquake

摘要：

This is a reconnaissance report on damage of bridges during the 2008 Wenchuan, China earthquake. Site investigation was conducted by the authors on August 10-14, 2008. Presented is damage of twelve bridges as well as discussion on possible damage mechanism. Characteristics of two near-field ground accelerations and Chinese practice on seismic design of bridges are also presented. It is found from the damage investigation that insufficient intensity of seismic design force, inadequate structural detailing for enhancing the ductility capacity and absence of unseating prevention devices resulted in the destructive damage of bridges.
