摘要：
This paper adopts the newly structured delta function and displacement function. Using two adjacent transition points as two interval terminals while beams buckle makes the interval [x(i-1),x(i)]. According to the Winkler's beam buckling theory on elastic foundation, we present the energy solutions of beams and then the exact solutions of buckling load of simple supported beams on bi-moduli elastic foundation.
