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 andor 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 andor mass matrices of the structure may be highly nonlinear about the design variables. Author
