Abstract
The chapter presents the optimum structural design for composite slender beams with complex curvature. The optimization process is performed using a genetic algorithm (GA), associated with a variational asymptotic method for the structural analysis. The stiffness control of arbitrary, complex sections under some design conditions is performed for composite beam where the geometrically nonlinear characteristic of the structure is considered. The objective function was defined as the weight, strength and fatigue life. The laminate thicknesses are to be determined optimally by defining a design index comprising a weighted average of the objective functions and determining the minimum.
