Structural investigation reveals altered stress-strain dynamics in glue laminated timber under slanting bending, suggesting current building codes misjudge pre-fracture structural safety.
Current rules do not take into account the peculiarities of glue laminated beams under the conditions of slanting bending. In fact, the rules do not consider the real change in the stress-strain behavior of such elements upon the load change from its initial application till fracture under the conditions of slanting bending due to the fact that material (wood) behavior in the construction is currently assumed as nominally elastic. What is more, this issue is not sufficiently studied either theoretically or experimentally.
