Structural Optimization on Geometrical Configuration and Element Sizing with Statical and Dynamical Constraints,
Abstract
In this paper, a bi-factor alpha-beta algorithm based on Kuhn-Tucker criteria about the minimal weight design of structure under statistical and dynamical constraints is presented. Among the constraints, frequency prohibited band is a new formulation which demands any characteristic frequency of the structure not to fall into a given frequency region. The design variables may cover sizes of the elements and/or coordinates of the nodes. The upper and lower bounds of each variable are specified. And the stress constraints based on full-stress criteria may also be taken into account. Satisfactory results have been obtained over various examples wherein the stiffness and/or mass matrices of the structure may be highly nonlinear about the design variables. (Author)
