基于锁铆连接传力可靠、强度优异的特征,提出了一种新型的内置铆接开孔冷弯薄壁型钢混凝土组合梁。以底部铆钉间距、截面宽度为变量,对内置铆接开孔冷弯薄壁型钢混凝土组合梁开展了四点弯曲试验,考察了该组合梁的破坏特征、承载性能和延性指标,试验结果表明:新型组合梁受弯时表现出良好的延性性能;底部铆钉间距小的组合梁延性较差;增大截面宽度可提高组合梁的极限承载力。采用ABAQUS有限元软件对该组合梁进行参数分析,重点探究五大关键参数对其力学性能的影响:有无混凝土包裹、混凝土强度、顶部铆钉间距、底部钢板厚度及截面高度 ...

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 ...
