| 摘 要： | 根据4个按延性需求设计的高性能混凝土剪力墙的试验结果,分析了轴压比、约束箍筋数量及范围等因素对高性能混凝土剪力墙的延性、耗能能力和破坏形态的影响,分析了分段约束箍筋对剪力墙截面的约束机理。研究结果表明,分段约束高强箍筋能有效增大高性能混凝土剪力墙截面的约束效果,根据轴压比和位移延性需求确定的分段约束箍筋数量和范围,可以明显改善高性能混凝土的脆性,使高性能混凝土剪力墙的延性指标达到设计要求。

| Abstract: | According to the experimental result of four high performance concrete shearwalls designed by ductility demands,the ductility,energy dissipation capacity and failure mode of high performance concrete shearwalls were analyzed,and they are affected by axial compression ratio,amount and range of confinement reinforcement,and the confining mechanism of piecewise confining stirrups.The results show that the confining effect of cross section can be improved efficiently by high strength piecewise confining stirrup... |
