This paper presents a numerical model based on the Finite Element Method (FEM), using Ansys® software with the Solid45, Plane42 and Combin39 elements to analyze wooden shear walls in light platform system. The displacements supplied by this model are compared with full-size prototypes tested according to the ASTM E72/98 standard, showing an excellent agreement. Four boundary conditions are also presented for a study of the shear wallsי diaphragmatic behavior. The geometric nonlinearity of the walls and the physical nonlinearity of the nail fasteners are considered in the numerical analyses.
