Shaking Table Model Test of Soil-Pile-Steel Structure Interaction System

This test is to study soil - structure interaction TLD damping control of the structure of shaking table model test series an integral part of the main purpose is to provide the corresponding comparative test data. In this experiment, the prominent issue is TLD, the upper layer structure and charged with three sub-system model-based frequency coordination between. In order to minimize soil model-based frequency, the use of the text - a kind of low-shear wave velocity of the simulated soil medium. Finally, through the soil - pile - the steel structure shaking table model test on the soil - structure interaction of the steel structure and dynamic characteristics of the impact of the earthquake response. The aim of the model test of the soil-pile foundation-steel structure system, that is one of the shaking table model test series for studying the effects of soil-structure interaction (SSI) on TLD\u27s performance to suppress the seismic responses of the structures, is to obtain the experimental data for comparison with the model test of the soil-pile foundation-steel structure-TLD system. The difficulty in the series tests is to keep the coordination among the fundamental frequencies of three subsystems of the superstructure, TLD and soil layer. For reducing the fundamental frequency of the soil layer as low as possible, a mixed model material with low shear wave velocity is developed and suggested to simulate the soil medium. Finally, the SSI effects on the dynamic characteristics and the seismic responses of the structures are discussed through the model test of the soil-pile foundation-steel structure system.
