矩形钢管-波折钢板组合墙端顶部承压性能与传力路径试验研究

Jianzhu Gangjiegou Jinzhan
矩形钢管-波折钢板组合墙是一种新型剪力墙，通过横置波折钢板连接两侧钢管形成预制钢构件，然后在钢管内及双波折钢板间填充混凝土形成组合墙。为研究矩形钢管-波折钢板组合墙在竖向荷载下的承载性能，以管间墙肢长度和栓钉间距为变化参数，完成了5个仅在墙端钢管混凝土柱顶加载的组合剪力墙试件抗压静力试验。在试验过程中，主要对加载端柱的竖向位移和组合墙三个不同高度截面应变进行了测量。试验结果表明，竖向荷载由组合墙边缘构件矩形钢管混凝土柱传递至剪力墙整体截面，需要一定的传力长度 ...

带孔板灌浆套管连接受弯性能研究

Jianzhu Gangjiegou Jinzhan
节点作为装配式结构的关键传力部件，其力学性能直接影响整体结构的安全性与可靠性。文中提出了一种带孔板内钢管灌浆套管连接节点，通过对12个足尺节点开展三点受弯试验，系统研究了该节点的传力机制和破坏模式，深入分析了内管长度、宽厚比、开孔参数、灌浆料钢纤维含量等变量对节点承载力、刚度与延性的影响规律。试验结果表明：该类节点的主要破坏模式为灌浆料受剪滑移伴随内管断裂，其中内管长度、开孔形状和栓钉布置形式对节点受弯性能影响显著。基于弹塑性计算理论，结合节点实际应变分布特征，建立了该类节点的受弯承载力计算公式 ...
