Abstract or Summary
  • Elasticity properties of wood studs are essential inputs for the structural analysis of wood-stud wall systems. A theoretical procedure was developed to determine the probability distributions for the deflection-load relations of stud samples. The procedure is based on the finite element analysis and a Monte- Carlo type simulation and accounts for the nonlinearity and local material variability caused by stud defects. The procedure was verified experimentally; the results displayed a good agreement between the theoretical and experimental values. A parameter study showed that the deflection-load curves were greatly affected by the local elasticity and strength of clear wood, grain angle, and knots. A listing of the computer program prepared is included. The program allows various options as to the types and geometry of stud defects.
