Reliability-Based Structural Optimization of Stochastic Structure Systems Considering Stability

Abstract:

The problem of failure mode analysis of stochastic structural systems, dealing with the design variables expression, reliability-based structural optimization and improved stability of girders, have been studied in this paper. Considering the material intensity, girder section area, panel thickness and loads as stochastic variables, a mathematical model of optimization is constructed. In the iterative procedure, the optimum vector method was adopted to optimize the object and the gradient step; and the optimum vector step have been used alternatively, and these can speed up the iterative procedure. The calculation of a numerical example shows this method is exact and free from the selection of optimum start point, further more the convergence is stable and fast.
