A Novel Whale Optimization Algorithm for the Design of Tuned Mass Dampers under Earthquake Excitations

This paper introduces a novel methodology for the optimum design of linear tuned mass dampers (TMDs) to improve seismic safety structures through Whale Optimization Algorithm (WOA). The algorithm is aimed reduce maximum horizontal peak displacement structure, and root mean square (RMS) response displacements as well. Furthermore, four additional objective functions, derived from multiple weighted combinations two previously mentioned parameters, are also studied in order obtain most efficient TMD configuration. differential evolution method (DEM), whose effectiveness has been demonstrated applications, an exhaustive search (ES) process, with precision decimal positions, used compare validate results computed WOA. Then, proposed applied 32-story case-study actual building, ground acceleration time histories considered assess its performance linear-elastic range. numerical show that based on WOA effective finding optimal configuration under earthquake loads. Finally, practical recommendations provided TMDs, robustness optimization demonstrated.
