Earthquake Response Control and Dynamic Tests Research on Bridge and Building Complex Structural System

In the paper, the bridge and building complex structural system is proposed as a new seismic structural system, and a steel frame complex structural model with the dissipation devices is designed in our research for a large scale shaking table dynamic test. Based on the new complex structural system and dynamic test results, the computation model, design parameters, earthquake response numerical analysis and the earthquake response decrease effect are mainly researched in our research. In this part, the basic concept system of bridge and building complex structural with energy dissipation devices is provided firstly, and a steel frame structural model with total weight 4.5 ton is designed to grasp the earthquake response of complex system. The research results show that the complex structure has a good reduction vibration effect; the acceleration response decreases nearly 50% in horizontal direction for building part. The acceleration response in deck of the bridge of the complex structure the range of decreases 9%∼30% compared to the pure bridge structure system, and the range of the decrease is 8% to 30% for the displacement responses. The dynamic test results show the new bridge and building complex structural system has ideal reduction vibration effect for both parts of bridge and building.
