In the experiment of lateral buckling of a beam we generally experience some difficulties in determining the buckling load, since the deformations gradually increase even in the vicinity of the critical load. To overcome these difficulties in the determination or the critical load, a method is proposed which can be induced from the relation between the load and deformation of the beam end. For the commonest deformation, this method gives satisfactory results in the light of the theoritical load for buckling. When the dimension of the beam runs to an extremity, very often different types of deformations appear. This paper further describes the deformations found in the beams of various dimensions. These are classified into three types, namely common, uncommon, and bending yield types. Mention is also made of the relation between each type of deformation and beam dimension, of the method of determining the buckling load and of the results gained thereby.
