介绍了用奇异函数和叠加法求解超静定刚架的一种新方法。当刚架的杆件受到较多的横向载荷作用时，或者当刚架的杆件为变截面时，这种方法将大大的简化计算。克服了力法求解超静定刚架的缺点，并保留其解法优点，即只需求解几个基本未知量。为此作者把本文提出的求解超静定刚架的新方法称为现代力法解法。
A new method of solving the statically indeterminate rigid frame with singular function and superposition method is introduced. This method greatly simplifies the calculation when the members of the frame are subject to more lateral loads or when the members of the frame are of variable cross-section. It overcomes the shortcoming of force method to solve the statically indeterminate rigid frame and keeps the advantages of its solution, that is, it only needs to solve a few basic unknowns. To this end, the author proposed the new method proposed in this paper to solve the statically indeterminate rigid frame as the modern force method.
