Title

Seismic Performance of Multiple Tuned Mass dampers in Suppressing Multi-Mode Responses of Building Structures

Abstract

Three mass-spring dampers were designed and fabricated to control the seismic responses of a 1/4-scale steel frame structure. The frequencies and damping ratios of the dampers and the structure were identified with free and forced vibration tests. The dampers with different combinations of springs and masses were installed on the structure for seismic response control. Parameters studied include the weight, frequency, and placement of the dampers. The sequential procedure developed in previous studies was applied to determine the sub-optimal locations of the dampers.
