【摘要】 通过对某大型火电厂主厂房纵向框架-剪力墙模型结构进行的伪静力试验,研究了此类工业厂房中纵向带边框柱剪力墙结构的抗震性能问题,并采用宏观有限元方法将这种剪力墙模型结构简化为一个多垂直杆模型,通过将竖向弹簧杆元放置在Gauss积分点处,不仅可以模拟出剪力墙结构的滞回曲线、骨架曲线以及延性等性能,还明显提高了计算效率。另外,比较计算结果与试验数据可以看出:两者在滞回曲线、延性等方面基本吻合,验证了该方法的准确性与有效性,可为推广使用提供参考。更多还原

【Abstract】 Based on pseudo static test, seismic behavior of the RC shear wall with boundary columns in the large capacity power plant’s main factory building has been studied. A multi-vertical-line-element model was proposed for shear wall through macro finite element analysis method. By using this model method in which the vertical spring elements were located at the points of Gaussian integration, hysteretic course, skeleton curve, and ductility characteristic of the shear walls were analyzed. After comparing computing results with test results, a good agreement between them indicates that the proposed multi-vertical-line-element model herein is reasonable and efficient in the nonlinear analysis of shear wall structure.更多还原
