摘要
给出计算壁式框架的两种方法,再以某10层大开洞剪力墙为例,采用通用有限元程序SAP2000,建立壁式框架模型,探讨杆件剪切变形对结构受力性能的影响,并给出合理建议。
Wall-frame method can be used to calculate the forces and displacements of shear wall structures with large openings, in which the linear rigidity of coupling wall-beams is larger than or close to the linear rigidity of coupling wall-columns. However, when the ratio of height to length is large, if the shear deformation is not considered in the wall-frame method, the results may be not accurate. Two methods of calculating structural internal force and deformation are given in this paper. A 10-story shear wall structure with large openings is analyzed by universal finite element method of SAP2000, the influence of shear deformation on working performance is discussed, and some reasonable suggestions are given to guide engineering practice.
