Abstract
The purpose of this paper is to illustrate a method of analysis of rectangular rigid frames, considering them as systems of spokewise connected members, by the Takabeya's method of slope distribution. It produces very rapid convergencies of approximate slopes in iteration. It is inevitable, however, that the preliminary computations become more complicated and troublesome than by the current method. To save these labours the author established simple and easily memorable rules by observing physical properties of a spoke system, and succeeded to mechanize the whole computation works.
The scope of this paper is confined to the frames without sidesways.
