高层剪力墙结构小墙肢的抗震设计探究

RESEARCH ON SEISMIC DESIGN OF SHORT WALL LIMB FOR HIGH-RISE SHEARWALL STRUCTURE

高层剪力墙结构抗震设计中,小墙肢常出现受剪截面超限或截面配筋过大的情况。从小墙肢截面计算高度取值、有效计算高度取值、墙肢受力状态、竖向分布筋配筋率和受拉分布筋屈服区长度等几个方面进行分析与讨论,并给出设计建议。

Seismic design of high-rise shearwall structure usually comes up with the problems that the section of short wall is inadequate because of shear force,and the reinforcement ratio of short wall is too high.This paper will analyze and discuss the factors being affected enormously by the calculation height of section,available calculation height of section,stress state,ratio of vertical reinforcement,yield region length of tensile reinforcement etc.,and suggestions on the engineering design are given as well.
