Ltd, Guangzhou, 510030, China)Abstract: Numberical simulation is used to analyze the joint of concrete-filled steel tube column and steel beam of crane with outer ring stiffeners. Mechanical properties in the elastic stage of the joint is studied. Simulation shows that the stress of ring stiffeners is well-proportioned and there is more strength residual in design. Stress convergence occours on the web plane and flange plane in the loading area. In the working situation, the strength of members reaches half of the design strength. It indicates that the joint has enough reserved strength to deal with special situation.
