TIMOSHENKO BEAM THEORIES FOR FOLDED PLATE EFFECT OF MULTISPAN GABLE FRAME STRUCTURES : Part I A case of asymmetric deformations

抄録

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 to the roof plate. Then, restrictions on the displacements of the roof plate enable to transform the gable frame structures with columns and end walls into Timoshenko beam theories. A case where the gable frame structures behave under asymmetric displacements with respect to the roof ridge is shown to demonstrate the procedure that gives precise solutions.
