Shake Table Test of Light-gauge Cold-formed Steel Frame with Friction / Viscous Damper and Sliding Base

(Part 2) Seismic Response Control of Three Story Frame Using Linked Fluid Inertia Mass Damper

Abstract

This study is on a shaking table test of Light-gauge Cold-formed Steel Frame. The test frame is a three-story frame scaled to nearly 1/2. In this paper, we show the test results and seismic response control effect using the friction damper and Linked Fluid Inertia Mass Damper (LFIMD). The friction damper is installed in the shear wall, and the LFIMD is installed between the adjacent floors. We designed a LFIMD that is constructed by three cylinders connected with link tubes, to simultaneously control story deflection of a three-story frame.
