［摘要］对一向少墙的高层钢筋混凝土结构的结构体系进行探讨，提出结合层剪力比判别结构体系的方法，并对少墙方向的结构抗侧力体系的组成进行了分析，以X向为少墙结构为例，指出了X向抗侧力体系包括X向布置的剪力墙、X向梁柱组成的框架、Y向墙和楼板组成的扁柱楼板框架，并建议限制扁柱楼板框架承担的抗侧力，而由剪力墙和梁柱框架承担全部水平地震作用。

Abstract:The structural system of high\|rise building with few shear walls in one direction was studied, and the method to identify the structural system combined with story shear ratio was put forward. The composition of the lateral resistant system of the structure in the direction with few shear walls was analyzed. Taking the structure with few shear walls in X direction as an example, the X-direction lateral resistant system consists of X-direction shear wall, X-direction beam-column frame and X-direction flat column-slab frame. It is suggested that the lateral force undertaken by the flat column-slab frame should be limited, the shear wall and the beam-column frame should bear all the horizontal seismic actions.

 

Keywords:structural system; story shear ratio; beam-column frame; flat column-slab frame; seismic design
