盘扣式脚手架节点抗弯性能研究

Jianzhu Gangjiegou Jinzhan
盘扣式脚手架节点由于具有半刚性特征，在荷载作用下呈现出明显的几何非线性特征，对结构稳定性产生不利影响。本文通过节点足尺试验与数值模拟相结合的方法对盘扣式脚手架节点的抗弯性能开展研究。首先，制作3组相同的足尺试验节点，测得了节点的抗弯刚度和抗弯极限承载力，并基于节点的荷载-位移曲线建立了盘扣式脚手架节点的三折线抗弯刚度计算模型；之后，利用ABAQUS有限元软件建立了试验节点的精细化有限元模型，通过模拟结果与试验结果的对比，验证了模型的准确性，获取了加载过程中的节点应力分布情况及破坏模式；最后 ...

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 ...
