| 摘 要： | 罕遇地震作用下的建筑结构往往处于弹塑性工作状态,但结构每个构件的损伤程度不尽相同.为了评价不同构件的损伤情况,编制了框架结构杆系振动模型弹塑性时程分析程序,对框架结构在罕遇地震作用下的损伤进行了分析.利用累计塑性变形倍率、平均塑性变形倍率和累计塑性转角与最大塑性转角的比值"S"对结构的损伤进行了评价.同时对结构各个杆件...

| Abstract: | Frame structures will be in elasto-plastic situation under rare earthquake.But damage of each member is not equal.A programme for elasto-plastic time history analysis is made,which is used to comput the damage of frame structure under rare earthquake.Average plastic deformation rate;cumulative plastic deformation rate and the ratio of cumulative plastic rotation and maximum plastic rotation are used to evaluate the damage of the frame structure.Plastic energy,damage ratior and residual deformation of each m... |
