Biaxial strength characteristics of wood-based structural panels were evaluated by
using analytical and experimental methods. Cruciform plywood specimens were tested
under biaxial tensile-tensile, compressive-compressive loadings in a symmetrically-jointed-
arm test fixture, which was mounted on a universal testing machine. Performance
of the test fixture was also evaluated during the tests....
The merits of the photoelastic coating technique as applied to
wood were evaluated. Comparative tests were made on 12 nominal
two-by-four Douglas Fir boards. The object of these tests was to
determine the limitations of this technique, such as accuracy and
complexity of experimental procedure. Correlation of the experimental
results...
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...
