［摘要］介紹了位于汶川地震震中映秀鎮(zhèn)漩口中學(xué)的建筑結(jié)構(gòu)震害情況，包括10個RC框架結(jié)構(gòu)和4個磚混結(jié)構(gòu)。針對極震區(qū)同一場地情況下框架結(jié)構(gòu)和磚混結(jié)構(gòu)的震害調(diào)查分析，提出了“巨震不塌”的目標(biāo)，并給出了提高結(jié)構(gòu)抗巨震倒塌能力的措施和建議。

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
