FEAFLO: A program for the analysis of layered wood systems☆

Abstract A finite element method for the analysis of planar layered wood systems is described. The method includes the effects of slip between layers due to fastener deformations, orthotropic material properties and gaps in layers. The method was used in developing program FEAFLO (Finite Element Analysis of FLOors). Data computed at each node include the deflection, rotations, fastener forces and for each layer the axial displacements, axial forces, moments, shears and extreme fiber stresses. The method was verified by comparing measured and predicted behavior for T-beams and wood joist floors. A listing of program FEAFLO, written in ANSI FORTRAN IV, is given. The input and output data for an example floor are also given.
