摘　　要：框架结构以其空间布置灵活、施工方便成为近年来多高层建筑结构常采用的一种结构形式,框架结构在水平荷载作用下如何准确、快速地计算其内力是结构初步设计常要解决的问题。将框架结构逐层分解为连续梁来计算其内力,力学概念清晰,计算过程程式化,是一种较为精确的算法,由于计算结果的精确性,因而是判断电算结果的一种可靠方法。　A new simplified method to calculate the internal forces of plane frames by using continuous beam principle is proposed in this paper.According to this method, the original structure is decomposed as a series continuous beams.The equilibrium equations of continuous beam are derived.Numerical results of calculations show that the precision is acceptable for engineering use and the method is reliable and helpful in the initial design.
