Elastic Buckling Analysis of Single Hat Rectangular Tubes

단일 모자형 사각 단면 부재의 탄성좌굴해석

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.
