Creep Buckling of Asymmetric Laminated Beam Columns


This paper examines the creep buckling response of asymmetric composite beam columns under general loading conditions. The material properties of the laminates are defined by the constitutive equations of the linear viscoelastic theory. The problem is formulated in terms of convolution integral operators and is solved by means of the quasi-elastic method. As a result of the analysis, a safe load limit for composite beam columns made of limited creep viscoelastic materials is determined. The creep buckling characteristics of composite beam columns are compared with the time-dependent behavior of respective homogeneous structures. It is observed that, by tailoring the composition and properties of asymmetric composite laminates, their long-term performance can be improved considerably.
