摘　　要：按照弹塑性性能等效、内力等效的原则,介绍了一种采用“等效柱”代替框剪结构中的剪力墙进行静力弹塑性分析的新方法,从而能够按照柱单元的塑性铰来模拟实际结构中剪力墙的塑性性能,并在实际工程中得到了应用,获取了静力弹塑性分析中剪力墙的各种有用的信息,其中包括层间位移、塑性铰出现的先后顺序、位置,以及塑性铰破坏的类型和破坏的程度等。结果表明,该方法是目前对带有剪力墙(筒体)结构进行静力弹塑性分析的有效方法。The new method of the static elasto-plastic analysis （Pushover analysis） is reviewed for structures with shear wall （tube structure）, 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）.
