［摘要］為解決高烈度地震區(qū)框架結(jié)構(gòu)抗側(cè)剛度小、冗余度較低的問題，提出對框架結(jié)構(gòu)增設(shè)黏滯阻尼墻與防屈曲支撐（BRB）的方法來提高其抗震性能。闡述了黏滯阻尼墻和BRB的工作機理，并結(jié)合工程實例分別對框架結(jié)構(gòu)進行四種工況下（純框架結(jié)構(gòu)、帶黏滯阻尼墻的框架結(jié)構(gòu)、帶BRB的框架結(jié)構(gòu)、帶黏滯阻尼墻和BRB的框架結(jié)構(gòu)）的小震、中震和大震抗震性能研究。結(jié)果表明，在小震和中震作用下黏滯阻尼墻和BRB既能提高框架結(jié)構(gòu)的抗側(cè)剛度，又能更好地耗散能量，框架結(jié)構(gòu)抗震性能較好，兩者能夠有機地結(jié)合起來；在大震作用下，黏滯阻尼墻和BRB滯回曲線飽滿，耗能效果明顯，是一種值得推廣的方式。

Abstract:In order to solve the problem of small lateral structural stiffness and small redundancy of the frame structure in high seismic intensity region, a method was proposed to add viscous damping wall and buckling restrained brace (BRB) in the frame structure to increase seismic performance. The working mechanism of viscous damping wall and BRB was illustrated, and practical engineering was combined to conduct seismic performance study of the frame structure with four working conditions including the frame structure only, the frame structure with viscous damping wall, the frame structure with BRB and the frame structure with viscous damping wall and BRB under the frequent earthquake, fortification earthquake and rare earthquake respectively. The results show that the frame structure with viscous damping wall and BRB not only can increase the lateral stiffness, but also can better dissipate energy under frequent earthquake and fortification earthquake, and the organic combination of frame structure with viscous damping wall and BRB has a better seismic performance. Under the rare earthquake, both the viscous damping wall and BRB have full hysteresis curves with an obvious effect of energy dissipation. Therefore, the frame structure with viscous damping wall and BRB is a design method worthy promotion.
