Column Analogy in Multi-Span Hinged Frames

A procedure is presented in which the method of column analogy, normally applicable to the analysis of single-span and closed frames, is extended for the analysis of multi-span frames with columns hinged to the ground. The extension involves consideration of conditions of rotations at the hinges. For illustration, a two-span hinged frame issolved in details. Results are in excellent agreement with values obtained using classical structural methods.
