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

Jianzhu Gangjiegou Jinzhan
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 ...

轴向荷载作用下小规格拉铆钉和普通螺栓疲劳性能对比研究

Jianzhu Gangjiegou Jinzhan
拉铆钉以其优异的防松动、抗疲劳和防腐性能以及较强的环境适应性等特点而广泛应用于航空航天、轨道交通、桥梁建筑等领域。为解决光伏支架中螺栓连接易产生疲劳的问题，现研究一种国产新型拉铆钉的轴向疲劳性能，用来代替普通螺栓连接以提高光伏支架的疲劳寿命。本文对LMY8和LMY10小规格拉铆钉及同规格的普通螺栓进行了轴向荷载作用下的静力试验和疲劳试验，并利用ABAQUS软件进行了拉铆钉铆接过程的模拟，利用FE-SAFE软件对拉铆钉疲劳寿命进行了模拟。研究结果表明：在同样条件下，铆钉的疲劳性能优于普通螺栓 ...
