摘　　要：本文首先列举了砌体结构在2008汶川大地震中的典型震害现象,通过这些现象分析了此次地震中砌体结构的震害特点,归纳了其震害规律和教训,总结了必须坚持的抗震原则及对今后砌体结构抗震设计的启示,同时,探讨了几个应该注意的重点抗震问题,提出了进一步加强砌体结构抗震性能的建议。文中指出,砌体结构只要坚持正确的抗震理念,加强构造措施,落实抗震规范的设计要求,保证施工质量,就能达到相应的抗震设防目标。Typical damage to masonry structures in 2008 Wenchuan earthquake were investigated. Based on the analysis of damage characteristics, this paper provide some lessons learnt from the strong earthquake disaster. Seismic principles, key problems, and design suggestions to improve the seismic capacity of masonry structures are proposed. It is concluded that, the corresponding seismic design objectives of masonry structures can be achieved if seismic concepts, structural details, design requirements, and construction quality are firmly held.
