摘　　要：提出了基于性能的抗震优化设计概念，并将其与最优设防烈度的决策方法结合起来，提出了基于最优设防烈度和损伤性能的抗震结构优化设计概念，并给出了一般性的优化设计过程。给出了指定设防烈度下基于损伤性能的抗震结构最小造价设计的数学模型，分析了优化模型的特点和求解策略。最后用一个数值算例说明了所提方法的全过程。in this paper, the concept of performance--based seismic optimum design (PBSOD) isproposed. Combining PBSOD with decision-making methods of optimal fortification intensity, the concept of optimum design of aseismic structures based on optimal fortification intensity and damage per-formance is put forward, and the general optimum design procedure is given. The minimum-costmathematical model of aseismic structures based on damage performance with given intensity is established, and the characteristics and solution strategies of the optimization model are analyzed. Finally,the whole process of the method is shown by a numerical example.
