| 摘 要： | 本文采用薄壳极限分析的一般变分原理,推导了在支管轴向受拉与受压下T 型管接头的极限载荷上限值表达式,利用非线性规划求出了最优极限载荷上限值。在理论分析的同时,还进行了钢质模型的实验研究,为理论分析的假设提供了基础。实测数据表明,计算值与试验值相当符合。

| Abstract: | Equations for determining upper bound limit load of tubular T-jointunder axial tension and compression of branch tube are derived by gene-ral variation principle of limit analysis of shell.Optimum bound limit lo-ad is obtained by using nonlinear programming method.Meanwhile expe-rimental research of steel models of tubular T-joint are carried out inShip Structural Laboratory of Shanghai Jiao Tong University.It providesbasis for assumptions of kinematically admissible velocity fields in theore-tical analysis.The computed values are quite close to the experimentaldata. |
