摘　　要：本文介绍了结构高等分析的概念和一般方法;给出了梁柱单元四项式表达,克服了轴力变号或趋于零时稳定函数表达不一致的缺点;通过一个设计实例进一步说明了高等分析用于设计时的优点与一般步骤,由于不需要对结构构件进行强度与稳定性验算。In this paper, the concept and general methods of advanced analysis are introduced. The formulation of four-termed element is proposed. It overcomes the non- consistence of the stability function when the sign of axial force P varies from positive to negative and vice versa P approaches to zero. The advantages and the design steps of the advanced analysis are further stated by a design example. The application of the advanced analysis in practical steel frame design is valuable because the checks of member strength and stability are not needed in advanced analysis.
