Many enhancements were made to timber in order to ensure its continuous application and commercialization. Glulam is designated as structural member with crucial attention needed to its jointing system. Similar to other large structural system the weakest point of glulam elements is the connections. Incomplete and limited information on guideline for tropical glulam design for glued-in rod has contributed to a set back of the Malaysian timber as the structural member. Due to this limitation, the standard design for glued-in rod using glulam is basically referred to the estimated extrapolation for solid timber guidelines. Therefore, the main objectives of glued-in rods for pull-out splice (GRPS) are to investigate the pull-out performance of glued-in rods connections using the most common species, Mengkulang glulam (strength group 5) for timber splice joints. The method is by determining shear strength of the glued-in steel rod for Mengkulang species and the types of failure modes were observed. The experimental were the tensile load carrying capacity for glued-in rod in glulam splice joints, to investigate the physical and mechanical properties of glulam with different diameters of rod, glue-line thickness and grain direction.
