摘要
分析了门式刚架结构在加设横梁拉杆前后刚架内力、刚架承载力、平面内稳定性、平面外稳定性的变化。通过将横梁拉杆加设在横梁上的不同部位,对比分析计算结果,得出相关结论,为类似工程项目提供加固设计参考,以期以最小经济代价取得最好加固效果。计算分析过程中同时考虑了横梁拉杆自身变形与柱顶位移间的变形协调。
The change of the internal force,carrying capacity,in-plane stability,out of plane stability of portal frame before and after setting the tension rod were analyzed. According to the different positions of the tension rod setting on the beam,the conclusion was got to help the designers in similar situation and aim to get more economical efficiency. At the same time,the compatibility of deformation between the tension rod and the top displacement of columns was considered.
