Study on Strengthening Glued-Laminated Timber with Aramid Cords and Properties of Composite Materials
This paper presents method of strengthening glued-laminated timber with aramid cords. In order to estimate the increase in load-bearing capacity, numerical analysis was carried out on three beams: unreinforced; reinforced with one layer of aramid cords; and reinforced with two layers of aramid cords. A preliminary numerical analysis showed a reduction of deflections of reinforced beams by about 11 to 14 % and a reduction of 19 to 25 % of normal stress.
