Experimental Study and Finite Element Analysis of Xconnections of Anyetang Special Steel Pipe

Abstract:

Two crossing Xconnections of Anyetang special steel pipe used for Henan Broadcast and TV Tower are investigated on the basis of practical projects.The paper presents the design of reducedscale test setup,experimental and finite element calculating results,and also the major factors influencing the load capacity of these special joints.The experimental results show that the special crossing joints have sufficient strength and rigidity,and can meet the design requirement. The experimental results agree well with finite element(FE) analysis,so this FE analytic model can be applied to other untested joints located in Henan TV tower.

Key words:TV tower; crossing joint; carrying capacity; test
