Study on Shaking Table Model Test of Soil-Pile-Steel Structure-TLD Interaction System
The effects of soil-structure interaction (SSI) on TLD's performance to suppress the seismic responses of structures are studied by a series of shaking table model tests. First, several important problems considered in test model design and solving techniques are presented in this paper. Then the results of the shaking table model test for the soil-pile foundation-steel structure-TLD interaction system are introduced and the TLD efficiencies to reduce the seismic responses of the structure are analyzed. Finally, effecting features of SSI on the TLD performance are discussed by comparing with the results of the shaking table model test for the steel structure-TLD system. In the last test, the steel structure is assumed to be built on the rigid foundation. The comparison between the test results shows that the TLD efficiencies to reduce the seismic responses of the structure decrease when the SSI effect is considered. The frequency feature and the intensity of the input seismic motion have important influence on this reduction. Therefore, the real conditions of the construction site and input seismic motion should be considered in the TLD design when the controlled structure is built on the soil site.
