In this paper, dynamic MOE and static MOE of short-length radiata pine specimens produced for finger jointing were measured using non-destructive technique and correlated to each other. In order to obtain reliable static MOE data, 36 mm thickness shooks as well as the matched samples of reduced thickness (15mm) were tested, and the effect of annual growth rings on dynamic and static MOE is also addressed. Mathematical correlations were fitted between the dynamic MOE for the 36 mm thick shooks and the static MOE of the 15 mm thick samples. The coefficient of determination for dynamic MOE group 4,00-7,99 GPa was the strongest (R 2 = 0,82) and the correlation strength was further improved for sorted quarter sawn samples (R 2 = 0,92). Finally, the correlation between static modulus of rupture (MOR) and dynamic MOE is discussed.
Highlights on glued laminated timber (glulam) of tropical hardwoods have attracted both local and foreign businesses. However, knowledge and technology regarding Malaysian timbers for the glulam application are still very limited. To improve the knowledge on structural performance of tropical timber glulam in fire occurrence, mechanical tests of burned glulam beams were conducted. The study focused on the effect of fire exposure to the mechanical properties of wood and bonding shear strength of the lamination. Based on the results of mechanical test of a selected species, strength and stiffness of timber were reduced due to the exposure to fire. Bonding shear strength of the lamination was also reduced.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
