通过基于云图法的概率地震易损性分析对黏滞阻尼器加固的非延性RC框架结构的抗震性能进行评价.以黏滞阻尼器的速度系数和加固后结构的等效阻尼比为设计变量,设计了9种不同的黏滞阻尼器加固方案.基于地震易损性分析对不同方案的加固效果进行了评价,发现采用黏滞阻尼器加固后,非延性RC框架结构的地震易损性降低,抗震性能得到较大的提高,并基于易损性曲线分析给出了非延性RC框架黏滞阻尼器加固的最佳方案决策.
The seismic performance of non-ductile RC frame strengthened with viscous damper was evaluated by the probability seismic vulnerability analysis based on cloud graph method. Taking the damping coefficient of viscous damper and the equivalent damping ratio of the strengthened structure as the design variables, Nine different kinds of viscous damper reinforcement schemes are designed.According to the seismic vulnerability analysis, the reinforcement effects of different schemes are evaluated and it is found that the seismic vulnerability of the non-ductile RC frame structure decreases with the use of viscous dampers, The seismic performance is greatly improved. Based on the analysis of the vulnerability curve, the optimal scheme for the reinforcement of the non-ductile RC frame viscous damper is given.
