| Abstract: | An approach to vulnerability-based optimization is proposed for earthquake- resistantframe structures by utilizing the constrained optimality criteria in this paper. First of all, aniterative forlnulation is deduced for the improvement of design variab1es in accordance withKuhn -Tuker condltions, then a method which is able to change the candidate fOr the con-straint boundafy by algebraic operation is suggested, and the formal steps of the algorithmused in this paper are provided. Finally, an example is given for numerical illustration. |
