方钢管混凝土柱全螺栓装配式连接节点抗震性能数值分析

为解决钢管混凝土柱与柱连接节点现场焊接带来的污染严重、建设效率低等问题，融合十字形芯筒方便加工和施工的优点，在课题组提出的自攻螺栓芯筒式柱节点基础上，提出一种新型连接节点，即内置十字形芯筒方钢管混凝土柱全螺栓装配式连接节点。基于该连接节点拟静力试验结果，利用ABAQUS软件建立数值分析模型，验证模拟方法的可靠性，并针对自攻螺栓、加劲肋和十字形芯筒不同构造组合开展参数化分析。研究结果表明：数值分析结果与试验结果吻合较好，验证了数值分析方法的可靠性；自攻螺栓有效抑制了法兰板的翘曲变形和相对开口 ...

外伸端板高强度螺栓抗拉连接设计方法研究

Jianzhu Gangjiegou Jinzhan, 2013
通过建立系列有限元分析模型研究了外伸端板高强度螺栓抗拉连接的力学性能,分析中考虑了不同端板厚度和螺栓直径变化对连接节点受力性能的影响。研究结果表明,高强度螺栓总拉力应由外加荷载引起的螺栓拉力和端板弯曲变形产生的撬力组成。通过分析拟合得到由外加荷载产生的螺栓拉力和螺栓撬力的分布模型和计算公式,并分别给出摩擦型和承压型两种类型的高强度螺栓考虑撬力影响抗拉连接承载力计算公式。
