Abstract:

A method of solving for the deflected shape of freely discontinuous plates and pavement slabs subjected to a variety of loads including transverse loads, in-plane forces, and externally applied couples is presented. The method is applicable to uniform and discontinuous plates and pavement slabs with freely-variable foundation support, including holes in the subgrade. This is a direct method for solving the discrete-element equations, which are an exact mathematical representation of the discrete-element model. Other reports (Refs 4 and 8) have described previous solutions. In order to improve those solutions, however, a method of varying the size of the discrete grid of the problem was needed. The model presented contains this capability by including variable increment lengths between stations. This gives the capability of greater accuracy in the solution near loads and changes in the stiffness of the slab. A computer program is presented which utilizes the equations developed from the variable increment model. Several example problems illustrate the method's advantages over previous methods. The results compare well with closed-form solutions and with other discrete-element methods.
