NUMERICAL ANALYSIS OF THE BOUNDARY CONDITIONS OF WOODEN SHEAR WALLS IN THE LIGHT PLATFORM SYSTEM

This paper presents a numerical model based on the Finite Element Method (FEM), using Ansys(registered) 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 wallsʹ diaphragmatic behavior. The geometric nonlinearity of the walls and the physical nonlinearity of the nail fasteners are considered in the numerical analyses.
