This study proposes a performance-based multiobjective optimization seismic retrofit method for steel moment-resisting frames.
The brittle joints of pre-Northridge steel moment-resisting frames are retrofitted to achieve ductility; the method involves determining the position and number of connections to be retrofitted.
The optimal solution is determined by applying the nondominated sorting genetic algorithm-II (NSGA-II), which acts as a multiobjective seismic retrofit optimization technique.
As objective functions, the initial cost for the connection retrofit and lifetime seismic damage cost were selected, and a seismic performance level below the 5% interstory drift ratio was employed as a constraint condition.
The proposed method was applied to the SAC benchmark three- and nine-story buildings, and several Pareto solutions were obtained.
The optimized retrofit solutions indicated that the lifetime seismic damage cost decreased as the initial retrofit cost increased.
Although every Pareto solution existed within a seismic performance boundary set by a constraint function, the seismic performance tended to increase with the initial retrofit cost.
Analysis and economic assessment of the relations among the initial retrofit cost, lifetime seismic damage cost, total cost, and seismic performance of the derived Pareto solution allow building owners to make seismic retrofit decisions more rationally.
