Multiple support excitations of elastic multi-span beams are studied. 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 studied by an approximate Pseudo Excitation Method calculating the power
spectral density matrix of the structural response vector.
