本法适用于杆件体系结构的分析。系根据子结构间内力或形变的传播和平衡条件,建立了以传播系数为元素的矩阵。具有方程组写出更为直接、解算全过程有物理性、并可使矩阵阶数大为降低等特点。所采用的传播系数和载常数,部分来自各种力或形变的传播法,但为了简明划(?)和适用,本文简要地作了新的表达和补充。这足将以往的传播法与现今所流行的矩阵法进行了结合,以期对结构的程序设计有所裨益。此外还介绍了按此法推导出的一套规律化的内力计算公式。
This method is applicable to the analysis of the bar structure. Based on the propagation and equilibrium conditions of internal forces or deformations between substructures, a matrix with propagation coefficients as elements was established. It is more straightforward to write the equations, solve the whole process of the physical, and make the matrix orders greatly reduced. The propagation coefficients and the load constants used are partly derived from the propagation methods of various forces or deformations. However, in order to simplify the definition and application, this article has briefly made new expressions and additions. This combines the past dissemination method with the matrix method that is popular nowadays, in the hope of benefitting the structural programming. In addition, a set of regular internal force calculation formulas derived from this method is also introduced.
