［摘要］中關村國防科技園A棟綜合樓是一棟特點鮮明的平面細腰形高層建筑，采用傳統(tǒng)框架-剪力墻結構扭轉(zhuǎn)效應明顯，建筑四角框架成為第一道抗震防線，結構體系存在安全隱患。通過計算對比分析，確定采用局部屈曲約束支撐框架與位于平面細腰部位的混凝土筒體組成的框架-剪力墻結構體系。設計過程中對屈曲約束支撐的布置原則、抗震性能改善效果及連接節(jié)點的抗震性能進行了詳細的分析，對一些關鍵構件明確了加強措施。分析結果表明，屈曲約束支撐減震技術與傳統(tǒng)混凝土結構體系有機結合，有效地改善了結構性態(tài)，提高了整體結構的抗扭、抗震性能。

Abstract:Complex building A of National Defense Science and Technology Park in Zhongguancun is a high-rise building with slender waist plane as its distinctive feature. It has an obvious torsional effect if the traditional frame-shear wall structure is adopted, and the frames in the four corners of the building consist of the first seismic line of defense, so there are some security risks in this traditional structural system. Through comparative analysis of the calculation results, frame-shear wall structural system was adopted including the frame with local buckling restrained braces and corewall located in slender waist plane. A detailed analysis was carried out in the process of design, such as the layout principles of the buckling restrained brace, improvement effect of seismic performance and seismic performance of connecting node, and the strengthening measures were taken on some crucial components. The analysis results show that, the organic combination of the buckling restrained brace energy dissipation and the traditional concrete structural system have effectively enhanced the behavior of the structure, and improved the ability of the overall structure to resistance the torsional effect and the seismic performance.
Keywords:slender waist plane; buckling restrained brace; concrete structure; frame-shear wall structure
