摘要:
在总结以往钢管混凝土柱与钢梁连接节点不足的基础上,提出了新型带外套管式钢管混凝土柱与钢梁单边螺栓连接节点,通过已有的试验研究和理论分析,考虑构件的初始几何缺陷和混凝土的塑性损伤本构,在与试验对比后,分别建立了带和不带外套管式钢管混凝土柱–钢梁端板连接节点的有限元模型.通过对模型进行单调加载,分析节点的破坏和工作机理;然后对节点进行参数分析,总结出影响节点初始刚度和承载力的主要因素;提出外套管式钢管混凝土柱–钢梁端板连接节点的M –0，实用模型.结果表明:带外套管式钢管混凝土–钢梁端板连接节点具有更大的初始刚度、承载力,提出节点的M-0,曲线实用计算方法与有限元计算出的M -6,曲线吻合较好,研究将为外套管式钢管混凝土柱-钢梁单边螺栓端板连接节点在实际工程中的应用提供参考.
Abstract:
The unilateral bolt connection nodes of new type concrete filled steel tubular columns with outershell and steel beam was put forward by summing up the previous deficiency of connection nodes. Based on theexperimental and theoretical analysis,in consideration of the initial geometric imperfections of steels and con-crete damaged plasticity model,end-plate connections for concrete filled steel tubular columns and steel beamwith outer-shell and without outer shell finite element models were established respectively.Under monotonicloading in finite element model,analysis the damage and working mechanism; according to parametric study a-nalysis the main factors of initial stiffiness and bearing capacity for joints and establish M-0,practical model fornew type joints. The results show that the joints with outer-shell have greater initial stiffness and bearing ca-pacity and better seismic performance.The M-0,models which was presented in this paper are reasonable andreliable.It can provide a reference for theory design and real engineering application.
