Free Lateral Vibration of an Axially Creeping Beam-Column under Initial Axial Compression.
Abstract
The free lateral vibration of a nonlinear viscoelastic beam-column subjected to an initial compressive axial load is considered. The constitutive law is formulated with a linear elastic term and with power functions of stress in the transient and steady creep terms, and is of the nonlinear generalized Kelvin type. By assuming that the stress caused by the oscillation is of much smaller magnitude than the initial stress, the problem is linearized. The problem is analyzed for five special viscoelastic models using small deformation theory, and numerical results are discussed for a stainless steel alloy. (Author)
