既有混凝土梁-耗能段组合节点力学性能试验研究

open access: yesJianzhu Gangjiegou Jinzhan
在既有混凝土框架结构中引入Y形偏心钢支撑,可得到新型既有混凝土框架-Y形偏心支撑结构,具有抗侧刚度大、抗震性能好和震后功能可恢复等特点。其中,既有混凝土梁-耗能段组合节点是实现新型结构预期性能的关键问题之一。基于此,设计四种基于端板连接、U形-侧面连接、U形-角钢螺栓连接、U形-三面连接的既有混凝土梁-耗能段组合节点试验模型,并进行往复加载试验研究,得到各节点的破坏模式、滞回曲线、骨架曲线、割线刚度、耗能能力和荷载-应变曲线。结果表明,基于端板连接、U形-侧面连接、U形-角钢螺栓连接的试件ECB-SL ...
