Abstract

An elastic buckling analysis of single hat rectangular tubes is carried out. Based on Bleich's buckling theory for elastically restrained plates, a method to estimate the compliance of the supporting plates for the buckling plate and to compensate the effects of compression force acting on the supporting plates is offered. Necessary assumptions which enable an analytic approach to be used are also given. The present results are compared with the finite element results obtained from ABAQUS.
