The wooden construction market is growing in Russia
In the last five years, the number of studies in the field of wooden structures for construction has increased significantly in Russia. Scientists have implemented 21 new GOST and JV and updated 11 more, and in 2022 they plan to develop seven more regulatory and technical documents. Pavel Smirnov, head of the Laboratory of load-bearing wooden structures at the Institute, told about this at the webinar "Modern wooden structures" from 100+ TechnoBuild and the V. A. Kucherenko Central Research Institute.
According to him, in Russia, the government pays special attention to the introduction of wooden structures for the construction of residential buildings. In 2021, the Ministry of Construction of Russia, the Ministry of Industry and Trade and the DOM Foundation will promote wooden construction.The Russian Federation even held a competition to develop standard design documentation for residential buildings and socio-cultural facilities using wooden load-bearing building structures.
The most promising technology is considered to be CLT panels. This is a multi-layered material, where boards connected by glue are used as layers. In Europe, there are already examples of the implementation of multi-storey buildings using CLT. The most famous is the WOOD Hotel in Norway, which is approximately 85 meters high. Segezha Group has started building four–storey CLT houses in Russia for its employees, which is the largest such project so far.
However, other technologies are actively developing, for example, frame-panel technology. So, in the city of Torzhok, a building was built with a frame made of LVL – glued veneer construction. Its special feature is its high factory readiness, environmental friendliness and durability, which is confirmed by the conducted research.
Wooden structures are actively used in the construction of public buildings.
"The traditional field of application of glued wooden structures and other types of structures are swimming pools and water parks," said Pavel Smirnov. – The most significant project in Russia is the Water Sports Palace in Kazan. The span of the building is 63 meters, the length is more than 100 meters. As a rule, coniferous species such as pine and spruce are used in projects with high humidity, this is due to the peculiarities of bonding structures."
Another area of widespread use of wooden structures is structures with a chemically aggressive environment, since wood is practically an inert material in this regard. The largest projects are mineral fertilizers warehouses in Berezniki and an ore warehouse at the Gremyachinsky GOK.
Glued wooden structures are also used in the construction of universal sports arenas, indoor tennis courts, and cultural and entertainment facilities. Abroad, they are actively used for the construction of office buildings and educational institutions, at transport infrastructure facilities – in Russia there are no such examples yet or very few.
TSNIISK plans to conduct five research projects this year. Among other things, to develop a domestic system of large-block house construction made of glued wood for residential and other buildings; to conduct research to determine the strength and elastic characteristics of glued laminated veneer lumber (LVL) under prolonged stress; to determine the normative values of strength and elastic characteristics of wood boards with oriented chips and others.
The new GOSTs will address the general technical conditions for solid wood wooden structures, cross-glued wood floor slabs for residential and public buildings, and other materials and technologies.
You can learn more in the recording of the webinar on YouTube. In addition, modern wooden structures will be discussed during the IX International Construction Forum and the 100+ TechnoBuild exhibition, which will be held from October 18 to 21 at the Yekaterinburg-Expo IEC.
