| Abstract: | A shaking table test on a three-story one-bay steel frame model with lead rubber dampers and their parallel connection with oil dampers is carried out to study the dynamic characteristics and seismic performance of the energy dissipation system. Test results show that, on one hand, combined energy dissipation system has favorable reducing vibration effects on structural displacement and acceleration. On the other hand, reducing vibration effects of the dampers can be improved by adding appropriate damping in the range of their suitable stiffness. Validity of the computational model and method is verified through comparison between the results of the shaking table test and numerical analysis. |
