In this paper, an optimum designmethod of laminated composites for load with deterministic variations is proposed. A deterministically variable load has a given variation represented by a domain of variation. The optimum configuration is obtained such that the laminate thickness is minimized under the constraint where the first ply failure does not occure with respect to the given loading region. The method used for the minimization is a nonlinear mathematical programming method. From the results, the optimum laminate construction approaches to that of quasi-isotropic laminates for load with variations. It is found that the most dangerous loading condition for laminated composites, which is called the control point of failure, is different depending on the characteristics of variations and the anisottopy of materials, and that it is not always the maximum loading point with respect to each component.
