中文摘要：
以山东邹城国际会展中心实际工程为研究背景,结构为多层框架,柱采用圆钢管或矩形钢管,梁采用钢桁架或H型钢.大跨度部分二层楼面钢桁架上下弦杆及腹杆均采用H型钢,与圆钢管柱采用销轴节点连接,为较理想的铰接.因楼面荷载大,现行规范没有销轴节点的设计方法,有必要进行试验研究.通过4组试验及有限元分析,表明销轴节点具有良好的传力性能和转动能力,承载性能满足设计要求,其设计方法可供类似工程参考.
英文摘要：
This paper took the project of Shandong Zoucheng International Convention Centre, a multi-story frame structure, as the research background. In this project, circular steel tubes and rectangular steel tubes were chosen for sections of columns, and steel truss and H-section steel were used for sections of beams. For instance, at the second floor, sections of the upper and underside chord members of large-span steel truss were made from H-section steel and were connected to circular steel tubes with pin joint. It could be treated as a relatively ideal hinge connection. There is heavy load on floor, and the current structural code does not include the design method of pin joint, therefore, it is necessary to conduct experimental analysis. Through four groups of experiments and finite element analysis, the result has indicated that the pin joint is equipped with good force transmission ability and rotation capacity, and it satisfies the design requirement of bearing capacity. The design method of pin joint in this paper can be used as a reference for similar projects.
