[摘要] 对四川汶川大地震中遭受地震灾害的底部框架．抗震墙砌体房屋的震害进行了调查分析，给出了不同建造年代的底部框架-抗震墙砌体房屋的震害特征和破坏状态；同时，对少量底层为局部框架或半框架上部为砌体房屋的震害也进行了调查分析，并对这类房屋的震害原因和震害经验进行了总结。探讨了底部框架．抗震墙砌体房屋薄弱楼层的部位与破坏状态的关系，指出了底部框架-抗震墙砌体房屋的抗震设计不应使底部楼层过强，而应尽量使底部框架．抗震墙与上部砌体房屋楼层的刚度较为均匀的设计概念。

Abstract: The damaged masonry buildings with frame and seisnuc-wallin the lower stories were surveyed and analyzed in the Wenchuan earthquake. Damage characteristics and failure state are presented of masonry buildings with frame and seismic-wallin the lower stories constructed at different times. At the same time, diagnoses are also happened on a few sublayer-local framework or half frame and top brick house wluch were damaged, the cause and experience of wluch are summarized. the relationship of the weak location and destructed state of masonry buildings with frame and seismic-wallin the lower stories. The design concept is presented that the stiffness of the bottom of the floor should not be too strong, but should keep the stiffness of sublayer frame anti-seismic wall and top brick house balancing.
Keywords: damage characteristics; weak floor; design conception
