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 ...

500 kV变压器卡扣式套管抗震试验及刚度分析

Gaoya dianqi
500 kV变压器卡扣式套管在地震作用中易损性较高，易发生套管绝缘油泄漏现象。为了研究卡扣式套管法兰的抗震性能，文中采用某型号500 kV卡扣式套管节点进行3组不同加载工况的拟静力侧推试验，对卡扣式法兰节点及瓷质套管在地震作用下的破坏现象和机理进行研究，并通过顶部位移的分解和抗弯刚度公式的推导，对卡扣式法兰节点在地震作用下的刚度变化进行分析。结果表明：地震作用下卡扣式套管往复的振动会使得瓷套管根部密封圈挤压变形移位，以及出现陶瓷碎裂的破坏现象；耳板薄弱处拉应力较大，与震害破坏现象一致 ...
