Comparative analysis of seismic toughness of existing RC frame buildings reinforced by BRB and viscous dampers
Based on the evaluation method in the Evaluation Standard for Seismic Reslience Assess-ment of Buildings(GB/T 38591-2020),three kinds of high-rise frame structures,i.e.,the origi-nal structure,the viscous damper reinforced structure and BRB(anti-buckling support)reinforced structure,are evaluated,and the toughness evaluation results of the three structures are compared.The results show that:the reduction of the repair cost of the viscous damper reinforcement is more significant than that of BRB reinforcement structure;both the viscous damper and the BRB re-inforcement can reduce the damage grade of the component and thus reduce the repair time,but the reduction of the repair time of the viscous damper reinforced structure is more obvi-ous;both the viscous damper reinforced structure and the BRB reinforced structure can re-duce the damage grade of the structure,thus significantly reducing the casualty rate,but the viscous damper reinforced structure has a more obvious reduction in the casualty rate.The results of this study can provide an important reference for the evaluation,comparison and improvement of toughness of reinforcement methods for high-rise frame structures.
