ROBUST DESIGN OF TMD SYSTEMS FOR THE SEISMIC RESPONSE CONTROL OF ASYMMETRIC SOFT STOREY BUILDING
Soft first storey buildings under seismic excitation with huge inter-storey drift at first floor level have been considered for the passive control with coupled tuned mass damper (CTMD) system. The design of tuned mass damper system for the multi degrees of freedom system for the response control under seismic excitation is associated with some efficiency and robustness issues. Robust control strategy is required for the effective reduction of response and damage in the structure. This paper discusses multi-objective optimal design of various tuned mass damper systems of higher robustness and efficiency for torsionally coupled seismically excited soft storey building. Objective functions have been considered as the displacement and acceleration along two translational directions as well as rotational components about the vertical axis. Non dominated sorting genetic algorithm (NSGA) has been used to obtain the design parameters of the CTMD systems.
