Prefabricated wood I-joist from araucaria hunsteinii flanges and oriented strand board (OSB) web / Muhammad Nadmin Md Hassan

This project was carried out with the objective of obtaining the strength properties of I-joist made from oriented strand board (OSB) web with L-butt joint and solid araucaria (araucaria hunsteinii) wood flanges. The result shows that sample 1 (A01) had the lowest value of MOR with 17.5 MPa and the lowest value of MOE was sample 2 (A02) with 9646 MPa. The highest value of MOE and MOR was by sample 3 (A03) with 13500 MPa and 24.8 MPa. The location of I-joist failure was at the web joint. Failures happen at the gap joint because of the glue were not spread evenly. Araucaria hunsteinii is a soft wood species and it was use to make part of l-joist flanges. This study proved that Araucaria hunsteinii can be used as flanges in I-joist system. This is because Araucaria hunsteinii and OSB can perform as a system of I-joist. This study try to promote Araucaria hunsteinii in building structure system.
