摘要
本又用试验验证厂钢管混凝土双肢柱刚性节点的弯矩按刚度分配的原则,从理论和实验上研究了宽翼缘加强环肋板式钢管混凝土刚性框架节点的工作性能,分析了它的工作机理及强度和刚度特性,确定了它的最危险截面位置并提出了简化设计方法,便于工程中应用。
The moment distribution method on the beam-column rigid joints of concrete filled steel tube in multi-storeyed framework has been verified with experiments.The theoretical and experimentical research on reinforc- ing ring-type rigid joints of concrete filled steel tube in multi-storeyed framework is carried out in this paper.The working mechanisms and the behavior of strength and deformation of the joints are discussed.The position of the dangerest section is determined.The practical designing formula is given and verified by experiments.
