本文討論搁置在地基上的框架的計算方法。地基被视为是半无限的弹性体。文中引入了地基上短梁的“杆件常数”的定义,因而使普通刚构分析中的“变形法”和“力矩分配法”等均得适用于地基上的框架計算。文中除簡略的敘述了計算理論外,并編制了大量常数表。应用本文的方法及数表,地基上的框架的分析工作可以迅捷的完成。
This article discusses the calculations of the framework that rests on the foundation. The foundation is considered to be a semi-infinite elastic body. In this paper, the definition of the “pole constant” of the short beam on the foundation is introduced. Therefore, the “deformation method” and “moment distribution method” in the ordinary rigid frame analysis are applicable to the frame calculation on the foundation. In addition to a brief description of the calculation theory, a large number of constant tables have been compiled. Using the method and number table of this paper, the analysis of the framework on the foundation can be completed quickly.
