Local Space

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.

High Rise Building

In this research, a reduced scale model of the composite high-rise building with steel reinforced concrete column, steel beam and reinforced concrete core tube was designed and tested by using the shake table test technology. The acceleration and displacement of the model were measured during the tests. The cracking pattern and failure mechanism were illustrated. Above the shake table test, the finite element analysis of the test mode was carried out. The main effort of the numerical analysis was focused on the selection of the nonlinear models. Based on the experiment results and the strategy of considering nonlinear property of the beam-column joint and the short beam of the concrete core wall were proposed. It is proved that the proposed strategy is effective and economical for seismic behavior assessment of such composite high-rise building structure system.

Rc Structure

An anti-seismic analysis about two structures (an irregular high-rise building and the previous structure using eccentrically braces) is performed to study their torsional vibration response in earthquake. The self-vibration character and relative displacement between different floors are compared. It is found that adding some eccentrically braces properly can reduce the response of torsional vibration and other seismic response of the structures efficiently. From the example mentioned in the paper, it is verified that this method is a simple and economical one.

Different Types

Based on brief introduction to the concept of vibration control, this paper discusses many different types of device for vibration control under wind load in high-rise buildings. By contrasting and analyzing the performance of each type of device, the classification and characteristics of the vibration control device for wind load are summarized, which could be used in choosing the proper device in controlling vibration under certain conditions.
