Abstract

In this study, ten full-scale Douglas fir wood beams, broken down into two groups, were tested under monotonic loading and a three-dimensional finite element method based model was developed to study the influence of longitudinal cracks on the flexural behavior of such beams. The test results indicated that the main failure modes of longitudinally cracked beams was flexural tensile failure at midspan or longitudinal shear failure near the beam ends. The load carrying capacity of the intact beams was found to be 39% higher than that of the cracked beams. A comparison of the test results with the numerical analysis results of the finite element model showed that the modelling error was less than 32% and thus is acceptable for prediction of such beams, considering the large uncertainty in the material properties and specimen preparation of the lab testing.
