[摘要] 依據(jù)《建筑抗震設(shè)計(jì)規(guī)范》( GB 50011-2010)，配合美國(guó)規(guī)范FEMA 356，提出一套消能減震結(jié)構(gòu)在多遇地震下的等值線(xiàn)性分析方法和一套適用于消能減震結(jié)構(gòu)在罕遇地震下的靜力非線(xiàn)性分析方法。此方法適用于位移型阻尼器和防屈曲支撐，不但可使消能減震結(jié)構(gòu)的結(jié)構(gòu)分析簡(jiǎn)化，并可避免受分析程序的限制，在不含阻尼器單元的分析程序上依然可做消能減震結(jié)構(gòu)在多遇地震和罕遇地震下的結(jié)構(gòu)分析。將此分析方法用于消能減震結(jié)構(gòu)的結(jié)構(gòu)分析，以證明此分析方法的可行性。

Abstract: This paper is mainly based on the building code of Cluna( GB 50011-2010), refemng to U.S.A.FEMA 356, puts forward an equivalent linear analysis method for structures with EDS( energy dissipation system),and a new substitute model of EDS( energy dissipation system)  on static nonlinear analysis. These methods not only can simplify and shorten the complex procedures during analyzing the structures with EDS( energy dissipation system), but also can avoid the restriction of different computer programs. It will enable the engineers to analyze the structural behavior on the programs without damper elements and consequently accelerate the application of energy dissipation tech. In addition, this paper shows the example using the new method for analysis of building with EDS( energy dissipation system)  to prove its feasibility.
Keywords: energy dissipation system; equivalent linear analysis method; static nonlinear analysis; displacement-dependent device; buckling-restrained brace
