Abstract A computer-based structural design methodology is presented for the least-weight design of planar frameworks subjected to multiple dynamic loads. The method makes use of dynamic finite element analysis, sensitivity analysis, first-order Taylor series approximations and the identification of response extrema to convert the time-parametric design problem into an explicit non-parametric form, which is solved iteratively using a dual optimization routine. The focus of the study is not to develop a general-purpose design capability but, rather, to examine the computational aspects of accounting for multiple dynamic loads in the design process. Two example truss designs under multiple regular sinusoidal wave loadings and multiple irregular earthquake loadings are presented.
