Shake Table Test of Complex High-Rise Building Equipped with Torsional Vibration Control Device

Abstract:

For many high-rising buildings, large local space is very useful for its special function needs, such as conference hall and hotel lobby. The shake table test results of a high-rising building with large local space show that 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. In this paper, the bidirectional Tuned Mass Damper (TMD) is employed for reducing the torsional vibration of such complex high-rise building structure. A reduced-scale model is design and constructed. A series of shake table tests are carried out and the test results indicate that the TMD system is very effective in torsional vibration control of structural system.
