The Damage in Arch Bridges during 2008 Wenchuan Earthquake
During the Wenchuan earthquake in 2008, many arch bridges in the seismic zone were damaged. The typical damage included: span collapsed, abutment and arch springing cracked, spandrel arch damaged, damage in the joint member between deck and main arch, damage out of arch plane. Some typical damage examples of the arch bridge are introduced in this paper. The causes and regular pattern features of the earthquake damage are analyzed, and the corresponding countermeasures are proposed.
