The study of orthotropic slabs, based on experiments on a large-scale model (16 x 9.9 x 1.6 m), made it possible to examine the precision and validity of various methods of calculation commonly employed by design engineers. The following methods were analyzed: 1. French regulation method; 2. Method of box girders; 3. Method of finite differences; 4. Fischer's method. Two new methods were developed in the course of this research project, making it possible to solve the problem of the continuous cantilevered orthotropic slab. This problem cannot be solved by conventional methods. Obviously, both methods are applicable to structures other than the orthotropic slab. The Pelikan-Esslinger method is widespread, and is applicable to an orthotropic slab of n continuous elastic spans. The results of various local tests made it possible to determine the points of concentration of stress, their value, and their distribution.
