摘要
采用Etabs对一错位转换高层结构进行了水平地震作用下的静力弹塑性(Pushover)分析。分析了侧推过程中的塑性铰出铰情况、结构位移变化情况、剪力在各竖向构件之间的传递情况、基底剪力—顶点位移曲线,在比较结构的能力曲线和需求谱基础上,对其抗震能力进行了初步的分析。研究分析表明,错位转换层的存在会使结构临界破坏状态出现较大的扭转反应;上部转换层下的框支柱和其上部墙体可能为结构最不利受力构件。
A high-rise building with stagger transfer structure has been Pushover analyzed with Etabs program. Plastic hinge occurring, change of structural displacement,transfer of shear force, base shear - top displacement of structure are analyzed when the structure is push in the horizontal direction, seismic capacity of that also analyzed elementarily. The research results show that there is a large torsional deformation in the critical damage state because of stagger transfer structure;columns supporting shear wall below the upper transfer story and shear wall on that may be the most disadvantageous component in the whole structure.
