【摘要】 对用套管加强的T型管节点在平面外弯矩作用下的极限强度作了参数化分析。同时将相应的套管以及管节点的几何参数对极限强度的影响进行评估,并且和未加强的T型管节点作了比较。在计算结果中可以得出在管节点的弦管和撑管的连接处用合适的套管加强,可以将管节点在平面外弯矩作用下的极限强度提高到3倍多。更多还原

【Abstract】 This paper presents the results of a parametric study to investigate the ultimate strength of sleeve reinforced hollow section T-joints subjected to out-plane bending.The effects of the relevant sleeve and the joint geometric parameters on the ultimate strength of these joints with different brace-chord combinations are evaluated and compared with those on un-reinforced joints.It is found that provision of an appropriately sleeve at the brace-chord intersection can provide ultimate strength enhancement up to three times to the un-reinforced joint.更多还原
