Current directions of development of domestic regulatory and technical documentation in the field of timber construction considering foreign experience

Abstract

Introduction. The concentration of a huge amount of forest resources on the territory of the Russian Federation allows to expand significantly the usage of wood in the construction of both low-rise and high-rise buildings and structures. The main directions of development of normative and technical documentation (NTD) in the field of wooden construction, demanded by the professional community, are presented. Materials and methods. A survey of wooden house building market participants was conducted to identify the most urgent problems in the field of wood application in the construction industry. The NTD of the USA, Canada and EU countries regulating the usage of wood in the construction industry were reviewed. The best practices implemented in foreign NTD and capable of serving as a reference point in the process of modernization of the domestic regulatory framework in the subject area under study have been identified. The questions of fire safety, earthquake resistance, as well as modern construction materials and products based on wood, used in the market of building wooden structures (WS) are considered. The composition and structure of NTD of the Russian Federation in the field of wood construction have been analyzed. Results. The analysis of domestic and foreign NTD has revealed a significant deficit in the part of normative and methodological support of construction from materials and products based on wood. Recommendations on updating, cancellation or revision of domestic normative-technical documents have been developed. Conclusions. The necessity of intensification of applied scientific researches for updating of NTD, in particular normative-methodical manuals and recommendations is formulated and substantiated. Proposals for structuring the system of NTD RF in the field of construction of wooden structures have been developed. The system of state standards in this area should cover technical specifications for individual materials and wood products describing their physical and mechanical properties and design characteristics. The proposed structure of NTD in the field of wooden construction has the possibility of dynamic development taking into account the development of the nomenclature of materials, calculation methods and applied technologies.
