摘要
采用大型有限元软件ABAQUS对某超限剪力墙结构进行罕遇地震作用下的动力弹塑性时程分析.提出了对应不同性能要求评定构件损伤的损伤指标,从结构整体地震响应与主要受力构件的损伤破坏层面上,对该超限剪力墙结构开展抗震性能评估.结果表明:在不同罕遇地震动作用下,结构各楼层最大层间位移角为1/154,小于规范限值,结构整体变形满足预期的性能目标;根据构件破坏状态评估可知,强震下结构部分剪力墙,连梁和框架梁发生了轻微损伤破坏,达到了预期制定的构件性能目标.
Dynamic elastic-plastic time history analysis of a high-rise shear wall building under strong ground motion was carried out by employing the finite element software ABAQUS. The damage index corresponding to different performance requirements was proposed. And based on seismic responses of the integral structure and damages of the structural components, seismic performances of the high-rise shear wall building were evaluated. Results show that the maximum inter-story drift angle of the building is 1/154, less than the limit defined in the specification. For the structural components, slight and frame beams under strong ground motions. In damage can be found partly in shear walls, coupling beams general, for integral deformations and component＇s damages,the seismic performance objective can be met.
