| 摘 要： | 依据收集到的313片混凝土剪力墙受剪性能试验资料,对我国现行《混凝土结构设计规范》推荐的剪力墙受剪承载力公式的可靠性进行了分析;分别采用我国规范混凝土剪力墙受剪承载力计算模式、混凝土偏心受压构件受剪承载力计算模式和美国ACI规范剪力墙受剪承载力计算模式,用回归分析方法建立了相应的剪力墙受剪承载力计算公式。分析结果表明,现行规范推荐的剪力墙受剪承载力公式的计算结果为试验结果的偏下限值,具有91.7%的保证率;而用上述3种计算模式建立的剪力墙受剪承载力公式,亦采用试验结果的偏下限值,均具有不低于95%的保证率。建议以我国规范的混凝土偏心受压构件受剪承载力计算模式为基础建立的公式,可作为混凝土剪力墙受剪承载力计算公式。
