Evaluation of Elastic Local Buckling Strength of Rectangular Hollow Section Members Considering Shear Bending Interaction
摘要
Elastic local buckling strength of rectangular hollow section members is theoretically derived considering coupling of adjacent plate elements and shear bending interaction. The effects of boundary conditions, loading conditions, and member shapes on the buckling strength are investigated. Finally, approximate formulas for calculating the buckling strength depending on bending moment gradient, cross section ratio, and aspect ratio are presented.
