[摘要] 使用防屈曲支撑对一栋钢筋混凝土框架-剪力墙结构进行了消能减震设计，提高了抗震设防目标。介绍了经过多道优化设计的减震方案，并用等效线性法对此进行了结构计算，使用SAP2000N结构非线性有限元软件进行了时程分析。该工程所使用的防屈曲支撑、预埋件焊点经过了结构试验检测，设置防屈曲支撑的混凝土框架梁柱节点也经过了类似的结构试验考核。研究表明防屈曲支撑消能减震技术能与传统混凝土结构体系有机结合，成为提高结构抗震性能、改进结构性态的一种有效的技术选择。

Abstract: With seisnuc reduction technology of a kind of BRB products,a concrete frame-wall structure is design and constructed, and the seismic performance target is enhanced. The optimized seismic reduction design is introduced, and the structural responses are calculated via the equivalent linear method. Some nonlinear time history analyses are performed with the program SAP2000N. The BRB products and the welded joint within the steel-embedded parts used in this building were tested beforehand, and the concrete beam-column joints were also tested in some parallel testing projects. This paper shows that the seisnuc reduction and energy dissipation technology involved in traditional concrete structures has become an effectively technical choice in improving buildings' seismic performance.
