摘要
针对某复杂的平面不规则高层框架剪力墙结构实际工程,建立SATWE和Midas Building两种不同力学模型,进行整体抗震性能分析,具体采用弹性时程分析和静力弹塑性推覆分析,分别得出该结构在多遇和罕遇地震作用下内力、位移等结果。根据平面不规则结构特点,在满足规范要求的前提下,通过调整结构模型的薄弱部位来提高结构的整体抗扭性能,为此类结构的抗震优化设计提供参考。
For a practical engineering of a complicated planar irregular high-rise frame-shear wall structure, two different mechanical models are established by SATWE and Midas Building to analyse the overall seismic performance by the method of elastic time-history analysis and elastic-plastic static pushover analysis, which respectively obtain the results of the internal force, displacement and so on under minute earthquake and disastrous earthquake. On the premise of the regulatory requirements, the weak parts of the structure model can be adjusted, according to the characteristics of irregular plane structure, to improve its overall torsional behavior which can provide references for the seismic structure optimization design of this type structure.
