STATIC BEHAVIOR OF STEPPED T-TYPE CR JOINTS
-
摘要: 采用非线性有限元程序对不等宽T型CR节点的静力工作性能进行了研究,并通过与4个节点试验数据的对比,验证了分析结果的正确性。采用该程序研究了弦杆厚度、支杆直径与弦杆宽度比以及弦杆高厚比对不等宽T型CR节点性能的影响。并把不等宽T型CR节点与相应的RR节点和十字型节点的性能进行了比较,得出了一些对工程设计有益的结论和建议。Abstract: Finite element analyses on the static behavior of stepped T type CR joints are conducted. The validity of the analytical results is verified by comparing with the experimental results of four joints. The effects of chord thickness, the ratio of the branch diameter to the chord width and the chord height to thickness on the static behavior of stepped T type CR joints are studied. The behavior of stepped T type CR joints is compared with corresponding RR joints and cross joints. Some useful conclusions and suggestions are put forward.
