“…Most structural optimization studies reported in the literature are concerned with the minimization of material consumption by using mathematical programming techniques without any regard to the uncertainties inherent in the design process [1][2][3][4][5][6][7][8][9] . In its general form, this minimum weight deterministic optimization problem is expressed as 7,9 : Minimize W= W i objective function (1) Subject to δ L j ≤ δ j ≤ δ U j j = 1,2,...,p (2)…”

“…excessive deflection). As suggested by Grierson and Schmit 7 for deterministic optimization, and by Frangopol 45 for reliability-based optimization, the major drawback to such an approach is that design decisions at one limit state must be made in the absence of explicit information as to their consequences at the other limit states of concern; for this reason previous design gains are very often negated and, at best a cumbersome iterative procedure (design-analysis-objective function evaluation-redesign-re-analysis-re-evaluation-...) is required to achieve a reasonably efficient design 7,9,45 .…”

ABSTRACTOptimization of structural systems under reliabilitybased performance constraints is an important problem at present receiving too little attention. This problem is investigated in this paper. In developing the reliabilitybased optimization approach to the design of framed structures, we review first the general formulation of the deterministic optimization problem and present some of the main features of two general-purpose deterministic optimization programs. A computer-automated reliability-based optimum design procedure is then presented by which the concept of reliability analysis with regard to both serviceability and ultimate performance constraints is combined with that of the minimum weight design to achieve an optimum trade-off between the global reliability and the total cost. The procedure is feasible for application in system optimization of both steel and reinforced concrete structures.
