A feasability study for strengthening timber beams with fibreglass
Authors: Theakston, F.H.
Description: The flexual theory in structural design has directed attention to the tensile stresses in structural members, since most materials are able to resist large compressive forces. This is particularly true for a material such as concrete which has little fibre strength. Concrete, however, can be strengthened by adding materials which have high tensile strength and by placing these materials at critical positions within the member. Steel reinforcing bars and welded wire meshes have been used with concrete for a great many years and reinforced concrete has become a recognized structural material. The reason for employing a non - homogenous material is, primarily, to obtain a balanced design in which compressive and tensile forces are distributed proportionally within the loaded member and to obtain a member which is more compact and sometimes more economical. Materials like steel, aluminum, cement asbestos and plywood may be shaped to distribute the applied forces and sections of angles, I beams, channels or other forms and are chosen by the designer for specific application.
