Strength of Beams and Columns with Creep Behavior

Abstract

Finite-element formulation for analysis of creep behavior of beams and columns subject to axial compressive load is presented. Temperature dependency of material properties, i.e., Young's modulus, yield strength, thermal expansion coefficient and creep coefficient, is considered. A new approach is proposed to predict the buckling time, and the results are compared with ones which are obtained by Hoff's idealization.
