Abstract:It presents the seismic damages of building structures, including 10 frame and 4 masonry structures, in Xuankou Middle School during Wenchuan Earthquake. Based on the investigation of damage results, including total collapse, partially collapse and other damage degrees in the same magistoseismic site near epicentro, the seismic design objective of ‘collapse prevention in mega earthquake’ is proposed. The suggestions to prevent collapse of building structures under mega earthquake are discussed.
Keywords:Wenchuan Earthquake; frame structure; masonry structure; collapse prevention in mega earthquake
