Numerical Response Analysis and Shaking Table Tests for Bridge and Building Complex Structural System (Part I: Complex Structure Dynamic Test Research)
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 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. The basic concept system of bridge and building complex structure with energy dissipation devices is provided firstly, and a steel frame structural model weighted 4.5 ton is designed. 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. Compared to the pure bridge structure system, the acceleration response in deck of the bridge of the complex structure decreases 9%~30%, and the displacement responses decrease is 8% to 30%. The dynamic test results showed the new bridge and building complex structural system has good reduction vibration effect for both parts of bridge and building.
