Abstract
Analytical results indicate that large deflection linearly viscoelastic columns with quasi-static follower loads under quasi-static conditions exhibit smaller deflections, smaller probabilities of failure and longer survival times than identical columns under the same loads but with dynamic effects caused solely by creep included. Column end shortening due to both curvature and compressive loads is also taken into account and the governing coupled nonlinear differential equations are solved numerically. The effects of end shortening on elastic and viscoelastic columns are discussed. Probabilistic column survivability due to creep buckling and material failure (delamination) are examined in detail.
