加强型空间相贯管节点受力性能分析

随着大跨度空间钢结构的发展，出现了许多新型的复杂空间节点形式，而我国现规范中对空间多杆系汇交管节点还没有强度计算公式，故对实际工程中出现的此类节点进行理论分析和试验研究就显得格外重要。本文对一内置加劲板加强型节点的受力性能进行了分析，得出了其极限承载力和破坏模式，对以后相关课题的研究具有参考意义。

Mechanics Behavior Research On Spatial Circular Hollow Section StrengtHened Joints

With the development of the large scale steel structure,more and more complex spacial joints have appeared.Since there is no expressions for its ultimate capacity to base on,it is very necessary to do some analysis to get the strength and the mode of failure by finite element analysis and tests.In this paper,Through comparing the mechanics behavior of two joints(with and without inside gusset plate),Structure behavior was understood under the influence of posting stiffener to tubular joints,Available design experience and theory foundation are provided to alike spatial CHS.
