摘要：

A complex mode approach is presented to analyze an externally damped viscoelastic Timoshenko beam subjected to distributed loads. The eigenfunctions of the original and adjoint equations are used to decouple the equations. Any conventional or nonstandard boundary conditions at beam ends can be handled with equal ease. Numerical response results are presented for random loads with spatial and temporal correlations.
