Abstract

The research aims to optimize viscous damper-based seismic reinforcement for single-span reinforced concrete frame structures. In this case, the fast non-dominated sorting genetic algorithm II (NSGA-II) based on multi-objective optimization is adopted to improve the crossover operator and the mutation operator in the algorithm, so as to ensure that the numbers of specific genes in the chromosomes remain the same across generations. Also, the research analyzes the variation curves of the objective functions with the increasing number of dampers when a structure is under three different seismic waves, thereby proposing a theory for selecting more economical reinforcement schemes on the premise that the structure’s safety is guaranteed. At last, it explores the damping effects of different Pareto optimal solutions suggested by the improved NSGA-II under three seismic waves to provide a reference for the spatial arrangement of dampers in single-span reinforced concrete frame structures.
