In this paper,design scenarios of a tuned mass damper (TMD) for seismically excited structures are ranked.Accordingly,10 design scenarios in two cases,namely unconstrained and constrained for the maximum TMD,are considered in this study.A free search of the TMD parameters is performed using a particle swarm optimization (PSO) algorithm for optimum tuning of TMD parameters.Furthermore,nine criteria are adopted with respect to functional,operational,and economic views.A technique for order performance by similarity to ideal solution (TOPSIS) is utilized for ranking the adopted design scenarios of TMD.Numerical studies are conducted on a 10-story building equipped with TMD.Simulation results indicate that the minimization of the maximum story displacement is the optimum design scenario of TMD for the seismic-excited structure in the unconstrained case for the maximum TMD stroke.Furthermore,H2 of the displacement vector of the structure exhibited optimum ranking among the adopted design scenarios in the constrained case for the maximum TMD stroke.The findings of this study can be useful and important in the optimum design of TMD parameters with respect to functional,operational,and economic perspectives.
