摘要

根据现浇混凝土结构与装配混凝土结构的耗能特点

建立了底部开缝后张拉预应力摇摆剪力墙结构模型

并采用数值模拟方法研究其抗震耗能性能

分析分布钢筋、预应力水平、轴压力等参数对其力学性能的影响

并与同类型整体现浇剪力墙进行了对比分析。结果表明:底部开缝后张拉预应力摇摆剪力墙结构具有一定的耗能能力

虽然相对于现浇剪力墙结构

其承载力较低

但变形能力较强

墙体损伤和残余变形较小

并且具有较好的自复位能力。

Abstract

Based on the seismic behavior of cast-in-place concrete structures and precast concrete structures

post-tensioned rocking shear wall with bottom slits was proposed in this paper.Seismic performance of the wall was studied with numerical simulation method and the effects of distribution mild reinforcement

post-tension level and axial-load level on the mechanical performance were also investigated. The study results indicated that although the strength of post-tensioned rocking shear walls decreases comparing with that of the normal shear walls

the proposed walls can achieve certain energy dissipation capacity. Furthermore

the walls can undergo large displacement with little damage and residual deformation

and have excellent self-centering ability.
