Design And Analysis of Energy Dissipation and Vibration Reduction of Reinforced Concrete Frame Structure

Abstract

Accompanying earthquake, some buildings that do not meet the seismic design requirements may tilt or even collapse. Many existing reinforced concrete frame structure buildings in China cannot meet the seismic requirements, these buildings need timely reinforcement. Energy dissipation technology helps the structure to consume seismic energy by adding dampers, which provides a new way for structural seismic reinforcement. In this paper, the friction damper is designed and applied to the reinforced concrete frame structure to achieve the effect of seismic reinforcement. The main work is as follows: a natural ground motion Chi-Chi wave from Taiwan is selected to carry out the time history analysis of the uncontrolled reinforced concrete frame structure and the structure with friction damper, and the interlayer displacement angle obtained by the analysis before and after the structure reinforcement is compared and analyzed. The analysis shows that the interlayer displacement angle is significantly smaller after the friction damper is added, which can effectively reduce the seismic response of the structure.
