【提要】按照彈塑性性能等效、內(nèi)力等效的原則，介紹了一種采用“等效柱”代替框剪結(jié)構(gòu)中的剪力墻進(jìn)行靜力彈塑性分析的新方法，從而能夠按照柱單元的塑性鉸來模擬實(shí)際結(jié)構(gòu)中剪力墻的塑性性能，并在實(shí)際工程中得到了應(yīng)用，獲取了靜力彈塑性分析中剪力墻的各種有用的信息，其中包括層間位移、 塑性鉸出現(xiàn)的先后順序、位置，以及塑性鉸破壞的類型和破壞的程度等。結(jié)果表明，該方法是目前對(duì)帶有剪力墻（筒體）結(jié)構(gòu)進(jìn)行靜力彈塑性分析的有效方法。

Abstract:The new method of the static elastoplastic analysis (Pushover analysis) is reviewed for structures with shear wall (tube structue),in which the shearwall is replaced by equivalent column based on the equivalent principal of the inelastic response and internal forces between the shearwall and equivalent column. The inelastic response of shear wall is modeled by plastic hinge of column element. This method is applied to many structures, and the useful results about shearwalls are acquired, including story drift, the sequence, location, failure modes and damage levels of plastic hinges produced.  It has been proved
 that the method is effect for elastoplastic analysis of structures with shear wall(core wall).
