| 摘 要： | 输电工程中输电塔架节点通常采用节点板连接的方式,单角钢杆件受轴向压力作用时,节点板处于偏心受力状态,常规的节点板受压承载力计算方法都是基于双角钢连接轴心受压得到的,与输电塔架节点板的受力存在明显差别。通过对2个输电塔架典型节点进行足尺试验和有限元分析,考察了单角钢连接节点板的受压性能和破坏模式,并利用多参数有限元分析结果,研究了用于单角钢连接节点板受压承载力的计算方法。试验研究表明,单角钢连接节点板受压时出现明显的板面外失稳,且节点板的变形呈现出弯曲伴随扭转的形式。通过对比分析表明,有限元分析结果与试验结果吻合较好。基于柱模型和板模型提出了单角钢连接节点板受压承载力的计算方法,分析表明,两种模型都能较好地预估单角钢连接节点板的受压承载力。

| Abstract: | The single angle-gusset plate connections are widely used in electric transmission towers.The gusset plates connected with single angle members are loaded under eccentricity condition.However,current design methods for statically loaded compressive gusset plates are achieved by analyzing the axial loaded gusset plates connected with double angle members.In this study,two full-scale tests and the finite element analysis were conducted to study the compressive behavior of gusset plates connected with single a... |
