Abstract
The problem of the nonlinear large deflection is treated in full consideration of friction between beam and supporting points, and analysed by the numerical method (R-K-G method) and the analytical one using elliptic integrals of the first, second kinds. The summary is as follows : (1) There exist two totally distinct conditions of deflection with different amount for the same vertical working load. (2) The maximum load resistibility becomes higher in the presence of friction. (3) The theoretical values agree well with the experimental results. (4) By using the reduction factors proposed here newly, the large deflection behaviour can be readily determined from the elementary simple linear bending theory.
