[摘要]分析了門式剛架結構在加設橫梁拉桿前后剛架內(nèi)力、剛架承載力、平面內(nèi)穩(wěn)定性、平面外穩(wěn)定性的變化。通過將橫梁拉桿加設在橫梁上的不同部位,對比分析計算結果,得出相關結論,為類似工程項目提供加固設計參考,以期以最小經(jīng)濟代價取得最好加固效果。計算分析過程中同時考慮了橫梁拉桿自身變形與柱頂位移間的變形協(xié)調(diào)。

[關鍵詞]門式剛架; 橫梁拉桿; 承載力; 變形協(xié)調(diào)

Abstract: 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.

Keywords: portal frame; tension rod; carrying capacity; compatibility of deformation
