［摘要］介绍了屈曲约束支撑（BRB）+ 黏滞阻尼器（VD）结构体系的减震原理，研究了体系的周期合理限值、体系的层间位移角限值，并提出BRB的逐步布置方法。以一实际工程为例，阐述了BRB+VD体系的实现过程，对比了BRB+VD，BRB，VD三种结构体系的减震效果，验证了BRB+VD结构体系的优越性。结果表明，提出的逐步布置方法能有效布置BRB，布置屈曲约束支撑和黏滞阻尼器的BRB+VD结构体系能明显提高结构的抗震性能，是高烈度地区复杂框架的合理消能体系。［关键词］屈曲约束支撑; 黏滞阻尼器; 减震; 逐步布置法中图分类号：TU352.1+2 文献标识码：A 文章编号：1002-848X(2016)11-0085-06
Analysis and research of BRB+VD energy dissipation systemChen Sicong, Zhou Yun（School of Civil Engineering, Guangzhou University, Guangzhou 510006, China）Abstract: The damping mechanism of buckling restrained braces (BRB) + viscous dampers (VD) structure system was introduced，the reasonable limit period and storey drift limit of such structure system were studied and further a step-setup method of BRB was proposed. Based on a practical structure, implementation procedures of BRB + VD system were elaborated. Compared the damping effect of structure system of BRB+VD, BRB, VD, the advantages of BRB+VD structure system were verified. Results show that the proposed step-setup method can arrange BRBs effectively. BRB+VD structure system can improve the seismic performance obviously, which is the reasonable energy dissipation system of complex frame structure in high-intensity areas.Keywords: buckling restrained brace; viscous damper; damping effect; step-setup method
