根据 4栋已建两层底框抗震墙砖房的设计资料及施工图 ,设计出了相应的普通纯框架结构房屋 ;对两者的经济性能作了定量评价。对位于地震设防烈度为 6 ,7度区的 3幢底框砖房综合楼与相应的框架结构 ,建立计算模型 ,输入 5条地震波 ,进行了罕遇地震作用下的弹塑性时程分析。在对比分析的基础上 ,对两种不同结构体系的抗震性能和经济指标做出了综合评估。 According to the design information and construction drawings of the four built-up two-story seismic wall brick house, the corresponding ordinary pure frame structure houses are designed; and the economic performance of the two buildings is quantitatively evaluated. Based on the three basement brick masonry buildings and their corresponding frame structures located in seismic fortification areas of 6 and 7 degrees, a computational model was set up and 5 seismic waves were input to analyze the elasto-plastic time-history under rare earthquakes. On the basis of comparative analysis, a comprehensive assessment of the seismic performance and economic indicators of two different structural systems is made.
