本文同时将多目标和多级优化设计理论应用于钢筋混凝土框架结构的抗震设计中，把整个优化过程分为两级优化来处理，第一级优化以结构的整体位移和结构重量两个目标函数为第一级优化目标进行优化设计。第二级优化以结构的延性为目标函数，对截面进行最优配筋计算，并计算了钢筋混凝土框架结构的算例。结果表明，本文提出的理论和计算方法是合理的。
At the same time, the multi-objective and multi-level optimization design theory is applied to the seismic design of reinforced concrete frame structures. The entire optimization process is divided into two levels of optimization to deal with, and the first stage is optimized to the structure’s overall displacement and structure weight. Optimize the design for the first level of optimization. The second-stage optimization takes the ductility of the structure as the objective function, calculates the optimal reinforcement of the cross-section, and calculates an example of a reinforced concrete frame structure. The results show that the theory and calculation methods proposed in this paper are reasonable.
