A state space method of optimal design of structures under transient dynamic excitation is developed and three problems are solved. It is shown that exploitation of the mathematical form of the equations of structural dynamics leads to significant computational efficiencies. A factor of five reduction in computing time is shown to be achievable, relative to more conventional nonlinear programming methods.
