Abstract

Thermal post-buckling behaviour of tapered columns is investigated through a finite element analysis. Columns of rectangular cross sections with breadth taper (depth being constant), depth taper (breadth being constant) and columns of circular cross sections with diameter taper are considered under simply-supported and clamped boundary conditions. Results for various cases are presented in the form of linear thermal buckling load and empirical formulae for the ratios of nonlinear thermal load to linear thermal buckling load.
