摘要:: 利用汶川8.0级地震特大发生后作者在极重灾区——四川省广元市青川县参加首批房屋应急评估工作期间收集的房屋震害资料,分析了砌体结构的震害特点和震害原因,对提高中小学砌体建筑抗震能力进行研究,从概念设计与计算分析两个方面对现行抗震设计规范的若干条文进行了讨论,提出了验算砌体结构抗倒塌能力的建议。

Abstract:: The earthquake damage of masonry buildings is collected in the earliest work of site urgent structural assessment in the extreme heavy disaster area Qingchuan county of Guangyuan city,Sichuan province just after the Wenchuan M_S8.0 earthquake.The features and causes of earthquake damage of masonry buildings are summarized and analyzed.Research work on enhancing the seismic capacity of masonry buildings of primary and middle school is presented.Discussion on the regulations of current seismic design code is made from the view of conceptual design and analytical calculation.Some suggestions are proposed to verify the anti-collapse capacity under strong earthquake.
