Performance of Iroko and Omo Cross Laminated Timber in Coastal Environmental Conditions

Abstract

This study explores the mechanical characteristics and behavior of Cross-Laminated Timber (CLT) panels made from Iroko and Omo wood species in coastal settings. The study focuses on bending strength (Modulus of Rupture), compressive strength, shear strength, and modulus of elasticity before and after exposure to moisture. Results reveal that both Iroko and Omo CLT panels demonstrate robust bending strength, but exposure to moisture led to slight reductions in strength, impacting adhesive bonding and causing delamination. Compressive strength, indicating a material’s ability to withstand compression forces, experienced minor decreases after moisture exposure. Notably, Omo CLT exhibited superior bonding, minimizing splitting under compression. Shear strength, representing resistance to internal layer sliding, showed marginal reductions after moisture exposure, with observed rolling shear failure. Modulus of Elasticity values reflected wood stiffness, with Iroko being less prone to deformation compared to Omo. These findings offer practical insights into the structural performance of Iroko and Omo CLT in coastal environments, providing valuable information for engineering applications and sustainable construction practices.
