Abstract
Fundamentals on transfer matrix method were established durling 1950's, and problems on round-off errors have already been pointed out. Although the solution method is of little interest from a viewpoint of practical application, it is recognized that transfer matrix method provides exact solution for ordinary differential equations based on various theories of structural members and the improvement of intermediate condition procedure is an important subject.
In this paper, an intermediate condition procedure in ordinary and modified transfer matrix method, which one of the authors studied previously, is investigated. Effectiveness of the procedure is confirmed by numerical results on statically indeterminate beam, multi-cell box girder and grillage girder bridge.
