Shaking Table Test of Building Mass Damper for Super High-Rise Buildings

Abstract

One of the technologies to suppress seismic responses in super high-rise or mid-to-high-rise buildings with a high aspect ratio is building mass dampers (BMDs). BMDs have a connecting layer with low horizontal stiffness located at a relatively high position of the building, where the upper part of the building acts as a tuned mass damper (TMD). BMDs that utilize a part of the building as a mass damper have an increased mass ratio. We verify the seismic response reduction effect of the BMD vibration control structure through numerical analysis and shaking table test using a six-story test model.
