某超限高层框架-剪力墙结构首先采用了SATWE和PMSAP两种有限元软件进行了整体计算分析,计算过程中优化了框架柱布置,并通过增加计算振型数量来提高有效质量系数,从而调整剪重比。计算结果显示,各项指标均满足现行规范要求。然后采用PKPM-SAUSAGE软件进行了动力弹塑性时程分析,结果表明层间位移角满足规范限值要求,确保达到“大震不倒”的抗震设防标准,可为同类超限结构性能化设计提供参考。
An over-limit high-rise frame-shear wall structure was first analyzed using SATWE and PMSAP finite element software. The calculation of the frame column layout was optimized, and the effective mass coefficient was increased by increasing the number of mode shapes. Adjust the cut-to-weight ratio. The calculation results show that all indicators meet the current regulatory requirements. Then, the PKPM-SAUSAGE software was used to analyze the dynamic elasto-plastic time history. The results show that the inter-layer displacement angle meets the specification limit requirements, ensuring that the “earthquake can’t fall down” seismic fortification standards can be used for the performance optimization of similar superstructures.
