PROBABILISTIC OPTIMAL DESIGN OF STRUCTURES USING SECOND-MOMENT CRITERIA.

Research output: Contribution to conferencePaper

Abstract

A general approach to probability-based optimal design of structures is presented. The emphasis here is to develop a practical approach to optimal design given random design parameters. The method is applicable to structures which are modeled using the finite element method. The second-moment design criterion is used to formulate the general design problem. A method for calculating the sensitivity coefficients is presented, which involves second-order design sensitivity analysis. A nonlinear programming technique is used to solve the problem. Numerical results are presented, where stiffness parameters are treated as random variables.
