消能减震结构的静力分析方法与工程应用

Linear analysis method for structures with EDS and its application

依据《建筑抗震设计规范》(GB 50011—2010),配合美国规范FEMA 356,提出一套消能减震结构在多遇地震下的等值线性分析方法和一套适用于消能减震结构在罕遇地震下的静力非线性分析方法。此方法适用于位移型阻尼器和防屈曲支撑,不但可使消能减震结构的结构分析简化,并可避免受分析程序的限制,在不含阻尼器单元的分析程序上依然可做消能减震结构在多遇地震和罕遇地震下的结构分析。将此分析方法用于消能减震结构的结构分析,以证明此分析方法的可行性。

This paper is mainly based on the building code of China(GB 50011—2010),referring to U.S.A.FEMA356,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.
