【摘要】 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。更多还原

【Abstract】 This method is suitable for the analysis of structures of member systems. The matrix is formed that it is based on the principles of propagation of internal force or defo(?)mation and equilibrium conditions in substructures, in which the factors of propagation are treated as the elements of the matrix.The merits of this method are that the simultaneous equations can be estabilished more directly, the whole process of solution has a clear physical conception and the orders of matrix can be greatly reduced.The propagation factors and loading constants are partially adopted from force or deformation propagation methods, meanwhile this paper provides some new expression or supplement in order to unify and apply them more conveniently, This paper is an attempt to combine the conventional propagation method with the current matrix method.It is anticipated that such an attempt would be beneficial to structural programming. In addition, a set of regularized formulas for calculating the internal forces by this method is presented.更多还原
