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 ...

Jianzhu Gangjiegou Jinzhan, 2009 本文在建立了高温下钢管混凝土柱-钢梁外加强环节点有限元分析模型的基础上,分析了在不同恒高温下环板宽度、钢管厚度、钢梁翼缘宽度和厚度、梁高等参数对节点抗弯承载力和初始刚度的影响。在此基础上建议了高温下节点抗弯承载力和初始刚度的简化计算方法,并用欧洲规范EC3的连接分类方法对高温下节点刚性进行了分析。

Jianzhu Gangjiegou Jinzhan, 2017 针对采用半刚性节点连接的双肢冷弯薄壁C形钢框架,采用拟静力试验与有限元模拟相结合的方法,对9榀双层单跨框架进行抗震性能分析。分析了节点螺栓直径、节点板厚度、螺栓间距及节点板加腋大小等参数对框架抗震性能的影响。结果表明:增大螺栓直径、增加节点板厚度和节点板加腋均能提高框架的承载力,改善框架的抗震性能。当螺栓间距小于80mm时,框架的承载力及抗震性能随间距的增大而增大;当螺栓间距大于80mm时,承载力及抗震性能受其影响较小。使用8.8级M16高强度螺栓,框架节点板产生了较大的滑移 ...
