摘　　要：在长期从事建筑工程的鉴定、改造与加固工作中，发现四川省部分抗震设防地区城镇临街的旧建筑中存在一种建于20世纪70—80年代较为普遍的特殊建筑结构形式——局部底层、局部底部2层混合底部框架—抗震墙砖房结构形式（文中简称为非完整的底部2层框架-抗震墙砖房结构）。为了研究该类房屋的抗震性能，采用通用大型有限元软件-ANSYS8．0，对该类结构的1个实际工程的地震响应进行计算分析，依据该实体结构的地震响应分析结果，指出该结构的薄弱部位以及计算应采用的模型和计算方法，为同类房屋的抗震加固和加固计算提供参考。Data from building appraisal, modification and strengthening show that hybrid subframe-shear wall structures-structures with partial one - story sabframe and partial two-story subframe supporting masonry structure （ in this paper, it is named TWO-STORY HYBRID SUBFRAME-SHEAR WALL MASONRY STRUCTRURE in short）-exist universally in some area in Sichuan province, these buildings were built in 70 s - 80 s. In order to study earthquake resistance performance of this building, in this paper, we applied general FEM package ANSYS to the dynamical analysis of one real two-story hybrid subframe supporting masonry structure, for which we input different sets of parameters before conducting spectrum and elastic time-series analysis, whose results lead us to the weak spot of the structure and practical model and computing methods, which can be served as the references of such structure earthquake resistance reinforcing and reinforcing calculation.
