The prestressed-expanded beams made of glued wood
Abstract
The paper presents the concept of applying prestress and expansion to beams made of glued wood. Some examples of calculations of the aforesaid in the paper beams with pre-tensioned and pre-compressed cables show the possibility of increasing more the twice the capacity. The experimental examination of the 3.00 meters beam confirm the theoretical results.
