The paper deals with the problem of an elastic-plastic bending of a beam with narrow rectangular cross section, under bending and shearing stress. In this case, a simply supported prismatic beam carrying one or two concentrated load is discussed. In our experiments, the observations were made from the deflections and the strain figures of yielding of mild steel beam. The data obtained thus by our tests have been compared with the theoritical formula which is derived from the Mises yield condition for perfect plastic body. The paper consists of three parts, namely a beam with a single central load, a beam with two symmetrical loads, and a beam with a load at any point of the span. The main part of the experimental results are the facts already recognised by the authorities ; but from the observations of the strain figures in the specimens, the type of yielding seen in case of narrow beam is different from that of a common thin section of beam, and it seems to the writer that such beam is under the same condisions of a tension bar under eccentric loading.
