Abstract

In this paper, a solution on improving a wooden bending beam by means of prestressing in proposed. The load-bearing capacity of a prestressed wooden beam is calculated. It has been established that the load-bearing capacity of wooden beams, which are bent in the direction of loading and fixed in this position, grows as compared to the load-bearing capacity of straight beams at the same length and the same surface area and shape of their cross sections.
