Torsional Vibration Control of High-Rise Building with Large Local Space by Using Tuned Mass Damper

Abstract:

According to the shake table test results of a high-rising building with large local space, the dynamic characteristics of such structure are complex and the torsional mode becomes the first mode, while the torsional responses under earthquake excitation, especially of the floor just above the large local space, are very remarkable. Special measures are required for such structural system for maintaining its seismic safety. In this research, the bidirectional Tuned Mass Damper (TMD) is employed for reducing the torsional vibration of the high-rising building with large local space. The optimization of the TMD parameters, such as natural frequency, damping ratios and mass ratio, is performed. The time history analysis results indicate that the proposed bidirectional TMD is very effective in torsional vibration control.
