为了提高传递影响系数法的计算效率和扩大其适用范围，引入子结构综合法的概念，发展了传递刚度系数法。在新方法中，要分析的结构被划分成子结构，每个子结构被划分成许多相同的基本元素。每个子结构通过基本单元的连接进行重构，在重构过程中消除了子结构内部节点的自由度，大大降低了计算量。此外，将与传递影响系数法相同的计算过程应用于由子结构重构的整个结构，从而进一步提高了计算效率。作为最基本的例子，使用本方法，算法制定的自由和强迫振动分析的直线梁结构。数值计算结果证实了本文方法的有效性。
The transfer stiffness coeficient method was developed in order to improve the computation efficiency and extend the applicability of the transfer influence coefficient method through introduction of the concept of the substructure synthesis method. In the new method, the structure to be analyzed is divided into substructures, each of which is divided into a number of identical fundamental elements. Each substructure is reconstructed by connection of the fundamental elements and the computation cost is markedly reduced by elimination of the degrees of freedom at the inner nodes of substructures in the process of reconstruction. In addition, the computation procedure, which is the same as that in the transfer influence coefficient method, is applied to the entire structure reconstructed from the substructures, for even greater improvement of the computation efficiency. As the most fundamental example of use of the present method, an algorithm is formulated for free and forced vibration analyses of a straightline beam structure. The validity of the present method is confirmed by the results of numerical computation.
