Abstract:The optimal decision model of the target value of performance based structural system reliability is established according to the cost-effective criterion in the present paper. Three types of optimal decision models are studied, which are conceptive model, parameter programming model and constraint relax model The conceptive model is inoperable because the objective function must be expressed as the function of the structural target reliability. The parameter programming model and constraint relax model are proved to be equivalent with Kuhn-Tucher conditions when the performance based structural system reliability constraints are all active. Finally the numerical examples of RC-frames for different earthquake-resistant performance are calculated.
