Abstract
The purpose of this study is to propose a systematic solution of the displacement method and stress method about the small displacement analysis of spatial rigid-jointed frames. A simple algorithm is chiefly used for calculating the displacement method. On the other hand, Because it is necessary to remodel a statically indeterminate structure to a statically determinate principal system, the stress method is unsuitable for analyzing complex structures. In this paper, the stress method will chiefly be described using the general inverse matrix. Moreover, by using the proposed analytical tecnique it is easy to structure an algorithm.
