| 摘 要： | 传统钢结构设计中将高强螺栓端板连接作为刚性节点,而实际情况下这种连接形式与计算结果有差异.采用有限元方法针对8种不同计算跨度的轻型门式刚架建立了三维整体有限元模型,分析了高强螺栓端板连接的节点刚度对门式刚架内力和位移的影响.计算结果表明,高强螺栓端板连接是一种半刚性连接形式,节点刚度对门式刚架整体结构的内力和变形将产生较大影响,在门式刚架的分析和设计中,应考虑节点半刚性的实际影响. |
| 关 键 词： | 半刚性 高强螺栓连接端板 三维有限元模型 轻型门式刚架 |

| Abstract: | The end-plate bolted connections are most calculated and designed as rigid connections in traditional designing,which leads to the significant difference between the calculation result and the real stressed state.Eight different span lightweight steel portal frames are analyzed with a finite element method in the paper.3D Integer models are made to analyze the influence on internal force and displacement.The results show that the end-plate bolted connections are semi-rigid connections,and the flexibility of the connections affects the behavior of the frames,and their influences can not be ignored in the steel portal frame design and analysis. |
| Keywords: | semi-rigid end-plate bolted connections 3D finite element models lightweight steel portal frame |
