In this paper, the behaviours of the beam of finite length on the elasto-plastic foundation are discussed in the case when the beam is subjected to single load which increases gradually. The results of this study are as follows : 1) The process of collapse of the beam can be expressed by two dimensionless values Ψ and γ as shown in figure (1). 2) The ultimate load and the form of collapse are calculated by using the equations (11)〜(17). 3) The maximum values of p_e/p_u lie on the line which is obtained by the equation (28). 4) Throughout the elasto-plastic region, we can classify the absolutely rigid beams and the infinitely long beams by using the equation (30). 5) The load-deformation of relations the beam are easily anticipated by the figure (5) together with solutions for the infinite long beam obtained in the previous paper.
