低轴压比单排双向配筋混凝土剪力墙结构性能试验研究

为了研究低、多层混凝土剪力墙结构的最小配筋率问题,本文对8片足尺的剪跨比0.8、轴压比0.08的混凝土剪力墙结构进行了低周反复荷载试验研究。试件采用双向单排配筋方式配筋,通过改变配筋间距,研究低轴压比下分布钢筋配筋率对剪力墙承载力、延性、滞回特性、耗能能力及破坏特征的影响。

Experimental Research on Structural Behaviors of the RC Shear Wall with Bi-directional Single Layer Reinforcement under Low Axial Force Ratio

In order to study the minimum reinforcement ratio of the multistory buildings,8 full-scale specimens with shear ratio equal to 0.8 and the axial-load ratio equal to 0.08 were tested to investigate the behavior of reinforcement concrete shear walls.Using the single reinforcement layers and different distributions of the reinforcement spacing(through the variation of the reinforcement ratio),the influence on the bearing capacity,energy dissipation capacity,ductility,stiffness and failure modes of the wall specimens under low axial-load ratio is analyzed.
