If the gap between two branch members is great , the joint is treated as t - or y - joint . or else , the minimum of the results obtained by the formula based upon steel tube flange shear failure mode and effective width failure mode is adapted for the tension branch joints 給出了矩形鋼管混凝土k型節點的間隙判斷公式,間隙較大時按t 、 y型節點計算;間隙較小時受拉支管節點承載力按沖剪破壞和有效寬度破壞模式計算,取較小值。
The full loading - displacement path had been traced , and the ultimate strength of the tubular joints had been determined . based on a series of numerical analysis of steel tubular t - joints , y - joints and k - joints of various geometric parameters , the effect of the various geometric parameters on ultimate strength had been investigated . the method of the reinforce joints had been offered 針對不同幾何參數的t 、 y 、 k型方主管圓支管鋼管相貫節點進行系統的數值模擬試驗,分析各幾何參數對節點靜極限承載力的影響,得出節點靜承載力隨各幾何參數的變化規律以及節點的破壞形式,并給出了相應的節點加強方案。
