高温下高强度螺栓连接性能的试验研究

, 2003
本文是针对鞍钢第二炼钢厂吊车梁加固而进行高温下高强螺栓连接性能的试验研究项目。试验中试件分别在200℃～450℃高温状态下加荷和在加温后冷却状态下加荷,得出了加热温度与滑移荷载（摩擦系数）的关系和摩擦系数的降低系数λ1与加热温度曲线的关系。最终得出在高温下高强螺栓应力松弛是促使滑移荷载下降的主要原因。提出了在200 ...

基于组件法的栓焊节点高温力学模型

Jianzhu Gangjiegou Jinzhan
钢框架梁柱连接节点的高温力学性能是影响火灾下钢框架结构抗连续倒塌性能的关键因素之一。基于组件法，将栓焊节点分解为翼缘拉压组件、连接板螺栓孔承压组件、螺栓受剪组件、梁腹板螺栓孔承压组件和螺栓滑移组件等基本组件，并分别对各组件的等效弹簧力学模型开展理论推导，最终建立了栓焊节点高温组件模型。基于已开展的栓焊节点抗火试验，构建了节点整体受力分析杆系模型，并通过对比有限元结果和试验结果，验证了组件模型的有效性和准确性。研究结果表明 ...
