COMPARISON BETWEEN ANALYTICAL AND NUMERICAL METHODS IN THE DETERMINATION OF THE DEFLECTION OF A SOLID PLATE

In the last decades, different methods have been developed for the analysis and design of structures. The objective of this work is to compare the effectiveness of the numerical methods with respect to the analytical method. For this, the deflection of a solid slab was determined, first with a uniformly distributed load, and then, with a uniform load plus an axial compression load, by the finite difference and finite element methods (STAAD-PRO). , compared to the analytical solution. The results show the comparison of the three methods, through tables and graphs for each of the load cases, in which it can be observed that the difference between the three is very small, when an adequate discretization is used
