Features of design and quality control of wooden structures, taking into account the strength class of wood

Abstract

The transition to strength classes in the design of wooden structures allows correctly assessing the level of reliability of the designed constructions. The article presents a comparison analysis of the safety factor values in the Russian regulative standards and those previously in force and assesses their impact on the reliability level. The influence of the transition to probabilistic normalization of the strength properties of elements and structures made of wood in general using strength classes is substantiated. The development of the approach will significantly improve the reliability and safety of wooden structures, especially large-span structures and multi-storey buildings.

Innovate designs of wooden beams for buildings and structures in the arctic zone of Russia

“…Due to the flammability and susceptibility to biological corrosion, wood is not often used [2]. However, with the development of the methodological basis for the calculation of wooden structures [3] effective protective coatings and impregnations of wood durability of wooden structures increases significantly and their use can now be justified for several objects, including transport [4] and in low-temperature conditions [5]. In addition, as experimental studies [6] show, the strength and frost resistance of glued wooden structures at low temperatures when using high-quality adhesive compositions is quite sufficient, and the strength of wood when freezing moisture temporarily increases.…”
