Buckling Analysis of the Tube Compression-bending Member in Elastic-Plastic State with ANSYS Zhicai Jiang1, a, Weilian Qu2,b 1,2(Hubei Key Laboratory of Roadway Bridge & Structure Engineering, Wuhan University of Technology, China,Wuhan 430070,China) a(whlgjzc@126.com),b(qwlian@sina.com) Keywords: compression-bending member; elastic-plastic instability; axial compression stiffness; buckling analysis Abstract: Stability is an important issue in steel structure design.When the steel member is subjected to elastic-plastic instability, the axial compression stiffness reduces with the increasing axial pressure and bending moment at end.
Introduction With the rapid development of building structures, compression-bending members are widely used in the field of civil engineering.
This made it applied commonly in the evaluation and assessment on the performance of real civil engineering structures[4].
Generally speaking, the steel components that are widely used in engineering have initial geometric defects.
