饱水状态下PFCB-钢筋桁架楼承板施工阶段力学性能研究

Jianzhu Gangjiegou Jinzhan
提出了一种新型免拆模钢筋桁架楼承板（PFCB-钢筋桁架楼承板），该楼承板由钢筋桁架和纤维水泥底板通过自攻螺钉和连接件预制连接而成。为研究PFCB-钢筋桁架楼承板在施工阶段的受力性能，并考虑施工时混凝土砂浆中水分或降水天气对纤维水泥板底模的影响，对PFCB-钢筋桁架楼承板进行了饱水状态下的承压能力试验。采用有限元软件对楼承板结构进行了参数化分析，得到了楼承板极限承载力与刚度的变化规律，发现PFCB-钢筋桁架楼承板在均布设计组合荷载以及集中荷载下性能良好，极限荷载下跨度为 3 600 ...

T形钢管混凝土柱-H形钢梁侧接板式节点承载力研究

Jianzhu Gangjiegou Jinzhan
为研究T形钢管混凝土柱-H形钢梁侧接板式节点的受力机理，对该节点进行了有限元模拟和理论分析研究。首先建立Abaqus有限元数值模型，通过试验结果验证了数值模型的合理性；根据节点构造特点，推导了该节点的受弯承载力和受剪承载力计算公式，并采用数值模型算例进行验证；基于计算公式分析不同变量对节点受弯承载力和受剪承载力的影响。研究结果表明：给出的有限元模型能够有效模拟侧接板式节点的工作状态和极限承载力；侧接板式节点的受弯破坏有4种破坏形态，通过合理构造可以确保首先出现钢梁翼缘受拉屈服破坏，实现节点的延性破坏 ...
