Absatract. The article describes the main advantages and disadvantages of wooden structures, considers the main methods for improving their operational reliability as well as ways to solve the problem of reducing the material consumption of wooden structures. The indicator determining the efficiency of using material resources and, therefore, the economy of the structure, the level of methods of design, production and operation of structures is the safety factor. Its acceptable value is determined based on the experience of design and operation, and is found as the ratio of the destructive load to the design load-bearing capacity. The article, based on the analysis of design and construction experience, discusses some structural methods and methods to improve the reliability and durability of wooden building structures, such as reinforcement and the use of a set of perforated fasteners in the form of corners, plates and supports. The elements of structures and technologies for manufacturing wooden building structures using reinforcement, as well as using various types of fasteners, considered in this work, are of the greatest interest and are relevant in modern construction both when designing new structures, and during repair, restoration and reinforcement.
Key words: wooden structures, operational reliability, safety factor, bearing capacity, durability, systems of fixtures, reinforcing of wooden designs.
