TIMOSHENKO BEAM THEORIES FOR FOLDED PLATE EFFECT OF MULTISPAN GABLE FRAME STRUCTURES : PartII A case of symmetric deformations

Abstract

Multispan gable frame structures with suitable beams and braces on the roof show a significant cubic folded plate effect that reduces the displacements and the stress resultants of each gable frame. The basic equations of the structures are derived by introducing an orthotropic plate theory into the roof plate. Then, the gable frame structures with columns and end walls are transformed into a Timoshenko beam on an elastic foundation by imposing restrictions on the displacements of the roof plate. A case where the gable frame structures behave under symmetric displacements with respect to the roof ridge is shown to demonstrate the procedure that gives precise solutions.
