摘要

采用有限元方法,改变结构的跨度和层数,对无边梁的板柱-剪力墙结构、带边梁的板柱-剪力墙结构和框架-剪力墙结构的动力特性进行对比分析。指出水平荷载作用下无边梁的板柱-剪力墙结构的侧移曲线是弯曲型的,而带边梁的板柱-剪力墙结构的侧移曲线是弯剪型,并且边梁可以有效提高板柱-剪力墙结构侧向刚度。
The dynamic characteristics of R/C slab column-shear wall structures with and without spandrel beams and frame-shear wall structures are analyzed and compared with finite element method when its span and story number are changed.It is pointed out that the lateral displacement curve of R/C slab column-shear wall structures without spandrel beams subjected to the lateral forces is belonged to the flexure type,while the lateral displacement curve of R/C flat plate-column-shear wall structures with spandrel beams subjected to the lateral forces,it is belonged to the flexure shearing type.Furthermore,it is concluded that the spandrel beams can improve the lateral stiffness of R/C slab-column-shear wall structures greatly.
