TITLE Performance Comparison of Location of Optimum TMD on Seismic Structures |
ABSTRACT The parameters of mechanical components of tuned mass dampers (TMDs) need to optimally tuned for an effective vibration reduction of seismic structures. Generally, metaheuristic algorithms are employed for this optimization problem. In the present study, location of a TMD on a seismic structure is investigated. The case structure is a 15-story building and the lowest story has a low stiffness to represent a base isolation level. The optimum TMD parameters are found for the placement of TMD on the top and base isolation level. The performance of TMD is best when it is on the top, but the optimum damping ratio value is small for a TMD positioned on the base isolation floor. The optimum TMDs are effective to reduce base isolation floor displacement and structural accelerations. |
