[提要] 對網(wǎng)架螺栓球節(jié)點中的錐頭強度進行了彈塑性有限元分析,得出其應(yīng)力分布、塑性區(qū)分布及極限承載力。并對錐頭的結(jié)構(gòu)特征進行分析,提出了設(shè)計建議。

The finite element method program is used to analyze the elastic-plastic strength of cones in one domestic construction. The stress distribution, the development process of plastic zones with the raising of external force and the bearing capacity of the cones are calculated. At last, the structural characteristics of cones are analyzed and some suggestions are posed.
Keywords: space truss; cone; elastic-plastic behaviour
