摘要
选取PKPM-Sausage和MIDAS-Building结构分析软件进行大震作用下的弹塑性时程分析,分析结果表明:在罕遇地震作用下,连梁最先出现损伤,框架梁有轻微破环,绝大部分剪力墙处于完好状态,连梁耗能效果显著。构件出铰顺序和损伤位置合理,能够满足结构抗震性能目标的要求。两款软件计算结果表明,结构的整体指标、薄弱部位、构件损伤程度等都基本吻合。建议在超限项目的设计中,为保证计算结果的可靠性,在进行弹塑性时程分析时可选取多种软件。
Dynamic Inelastic time-history analysis is carried out by the software of PKPM-Sausage and MI- DAS-Building under rare earthquakes. The results show that under rare earthquakes,damage firstly occurs on coupling beams ; frame beams suffer little damage ; the majority of shear walls are in good condition;cou- pling beams consume seismic energy remarkably. The order and position are reasonable. Seismic perform- ance objectives of structure can meet the code requirements. The analysis results about two software indi cate that the overall index, weak position, the degree of damage are basically consistent. In the design of the overrun project, in order to ensure the reliability of the calculation results, a variety of software can be se lected for the elastoplastic time history analysis.
