| 摘 要： | 采用扒钉、CFRP布(碳纤维增强塑料布)和钢箍3种材料加固古建筑木构架榫卯节点.通过人工加载方式,进行低周反复加载试验,分析3种材料加固后榫卯节点M-θ(弯矩-转角)滞回曲线、M-θ均值骨架曲线、耗能能力、刚度退化和延性的变化,对比了3种材料加固榫卯节点的抗震效果,并对3种材料在木构架加固工程中的应用提出建议.结果表明:榫卯节点加固前后均有良好的变形能力；CFRP布加固节点承载力＞钢箍加固节点承载力＞扒钉加固节点承载力；CFRP布加固节点耗能能力＞钢箍加固节点耗能能力＞扒钉加固节点耗能能力；CFRP布加固节点刚度退化＞扒钉加固节点刚度退化＞钢箍加固节点刚度退化；CFRP布加固节点延性＞扒钉加固节点延性＞钢箍加固节点延性.建议扒钉用于小型木构架加固；CFRP布用于中小型木构架加固；钢箍用于中大型木构架加固.
