大跨度楼面桁架销轴节点承载性能试验研究
Experimental Study on Floor Truss Pinned Connection in Large-span Steel Structure
摘要
Abstract
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.关键词
