REINFORCEMENT OF COMPOSITE WOODEN STRUCTURES MATERIALS, CONDITION AND PROSPECTS

Abstract

Today, there is a growing need in the construction industry for the introduction of ecological urban space and the use of materials from renewable natural resources, one of such building materials from ancient times was wood.Temples, castles, houses, bridges and other structures have been erected all over the world sinceancient times with the help of wooden structures.A large number of buildings and structures made of wood have been operating successfully for 300-400 years and are vivid examples of the durability of these structures. Nowadays, wooden construction is developing rapidly with the development of new technologies. After all, new woodworking technologies allow obtaining a spliced array ofwood, which solves many different issues of wood as a structural material. Recently, the constructionof glued timber (GT), which is often used to cover large spans (more than 100 m) and the constructionof cross-laminated timber (CLT) or CLT (cross laminated timber), which are often from an oddnumber of layers of boards with their mutually perpendicular arrangement in adjacent layers. Panels used in panel and panel-frame construction of buildings of various complexity of architectural form and number of storeys are made of CLT. Inworks [1-3] studies of efficiency and CLT and methods of their calculation are described in moredetail. However, some building requirements, such as the conditions for limiting the building height,when the use of relatively large cross-sections of plywood constructions, calculated in compliance with the requirements of the boundary conditions, is not possible. Therefore, the search and study of modified efficiencies, including reinforced ones, to increase the bearing capacity while reducing their cross section is becoming increasingly important.This publication is devoted to the review of the conducted researches reinforced and reinforcedwith composite materials of various efficiencies.
