A direct method of solving for deflected shapes of freely discontinuous pavement slabs subjected to a variety of loads including transverse loads in plane forces and externally applied couples is presented. The method applies to slabs with freely variable foundation support including holes in the subgrade and rapidly solves finite element slab equations developed, unhindered by closure parameters necessary in iterative techniques of solution. A computer program uses equations and techniques developed. Sample problems illustrate generality of. the method and convenience to the user. Results compare well with closed-form solutions and with previous solutions developed by other techniques.
