Abstract
The seismic behavior of elastic multi-span beams subjected to multiple support excitations is studied by means of a random vibration approach. Based on the common set of equations of motion an efficient formulation is developed in order to reduce the degrees of freedom. The resulting equations are formally identical to those that are valid for structures under uniform support excitations. Stationary random multiple support excitation is entirely performed by an approximate Pseudo Excitation Method calculating the power spectral density matrix of the structural response vector.
