Unlike reinforced concrete and metal, prestressing is used much less frequently in wood. Wood began to apply in 1860 and continued to be used in prestressed structures. But at the same time it faced some problems. To minimize the impact of these factors it is recommended to take the following measures: 1) To use special knots with the most increased contact surface for prevention of wood deformation in them. For such a node, the author of this article received a patent for a utility model; 2) carefully control the humidity and prevent it from changing during operation; 3) prestress is set with some margin due to the rheological properties of wood, or during operation to increase it.
