摘要
近几十年来,钢管混凝土结构在土木工程的各个领域得到广泛应用。在高层和超高层建筑中,由于钢管混凝土柱的特殊构造,促进了研究者对梁—柱连接方面的研究。目前,工程实践中采用的节点型式多种多样,各种特性不一的节点型式,在引入框架设计时,大都假设为刚接或铰接节点,这与节点的受力特性有一定的差异。通过对组合梁—钢管混凝土节点的静载试验,模拟钢—混凝土组合梁—钢管混凝土柱节点区域负弯矩特性,研究节点的受力性能,并将所测得的节点区域梁、钢柱、核心混凝土等的试验结果与有限元分析进行比较、校核,修正有限元分析模型,寻求这种组合结构受力时的一些规律,为工程实践提供指导作用。
The steel-concrete composite structure has been widely used in all fields of civil engineering recently,for it＇s specificity the scholars studied the characteristics of beam-column connection area in the high-rise and ultra-high-rise buildings.A variety of node types have been adopted in engineering practice.In the framework designing,the different node types are assumed to be rigid or hinged node mostly,this is different from the node characteristics.In this study,in order to simulate and investigate the joint negative moment performance of reinforced concrete beam and steel-tube concrete pole,the experiment regarding the capacity of the steel-concrete joint under static loading was conducted.Besides,a finite element analysis was also performed.By comparing the experimental and numerical results,finite element model of this composite structure was verified and improved;some general conclusion regarding this composite structure was made.This study provides a good guidance for engineering practice.
