偏心支撑框架的设计计算方法

我国《建筑抗震设计规范》(GB5 0 0 11- 2 0 0 1)规定 ,8度以上宜采用偏心支撑 ,但我国至今没有一个自行设计的工程用过这种支撑。参考美国计算例题、相关规范 ,并依据我国规范 ,对偏心支撑框架的实际计算方法进行讨论 ,总结出适合我国规范和实际情况的偏心支撑框架设计计算方法。其中 ,重点介绍了各杆件的内力计算、消能梁段的设计、非消能梁段的设计、支撑的设计、柱的设计等 ,给工程设计提供理论基础和实用方法 ,有助于设计人员对该体系设计过程的了解和此种支撑的推广应用

THE DESIGN AND CALCULATION OF ECCENTRICALLY BRACED FRAMES

Code for Seismic Design of Building”(GB 50011-2001) stipulates that eccentrically braced frames are used for buildings with aseismic fortification intensity 8 or above,but they have not been yet used up to present time for buildings designed by domestic designers.The practical calculations of eccentrically braced frames are discussed with reference to the US examples and codes on the basis of the specifications of China.The calculations place emphasis on the internal force of elements,the design of links,the design of beams out side the links,the design of braces,the design of columns and so on.They provide the theoretical bases and practical way for project design,and are helpful to the comprehension of the design procedures for the designers and popularization of this system.
