［摘要］异形剪力墙稳定验算主要包括翼缘、腹板局部稳定验算和墙肢整体稳定验算。其中，翼缘、腹板局部稳定问题是二维受压构件的稳定问题，而《高层建筑混凝土结构技术规程》 (JGJ 3—2010)提供的验算方法的依据是一维压杆稳定验算的欧拉公式，该方法理论依据不足。根据异形剪力墙翼缘、腹板的不同边界条件及平板屈曲理论推导出异形剪力墙局部稳定验算公式，同时对异形剪力墙整体稳定的规范验算公式及验算条件提出了改进意见。

Abstract:The stability calculation of special\|shaped shear wall includes flange and web local stability and wall column overall stability calculations. Flange and web local stability problems are two-dimensional compression member stability problems, but  a calculation as Euler formula which based on one-dimensional compression member  is provided in Technical specification for concrete structures of tall building (JGJ 3—2010) for concrete structures in high-rise buildings. The method in the code is lack of theory basis. The local stability calculation formula was derived according to the different kinds of boundary conditions of flange or web of special-shaped shear wall and the plate buckling theory. In the meantime, the improvements were put forward for the overall stability calculation formula and calculation conditions for the special-shaped shear wall in the code.

Keywords:plate buckling theory; Euler formula; special-shaped shear walls; local stability; overall stability
