WOODEN BEAMS WORK IN THE CONDITIONSOF SLANTING BEND AT DIFFERENT ANGLES OF INCLINATION

Abstract

Modern building wood has several benefits, such as light weight, easy manufacture, firmness and relatively cheap cost, constant natural renewability, which help to create new architectural forms.

The behavior of  beams  which are under the conditions of slanting bending is currently poorly known. Operative rules and existing studies  do not address the real behavior of the beams under the conditions of slanting bending or make it impossible to establish the neutral line position and the stress-strain distribution of the cross section at various stages of loading the construction in general.

Current rules do not take into account the peculiarities of 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.

This article is devoted to the study of the working peculiarities of wood beams  boards under the conditions of slanting bending.

The purpose of this research is the study of the working peculiarities of glue laminated beams beams in «Lira» software under the conditions of unsymmetrical bending.
