Abstract
Abstract Recently, the utilization of timber as building materials was very promising for now and future. As renewable resources they have high mechanical properties, lightweight, environmentally friendly and economic. One of the most durable engineered wood products is glued-laminated timber which commonly called Glulam. Glulam is a material made of several layers of wood glued together with waterproof adhesive at specific pressure and temperature. The benefit of Glulam is enable to produce the structural member with longer span compared with solid wood. In other to obtain the structural Glulam with longer span, it required the finger joint connection on lamina layer. This study aims at to find out the effectiveness finger joint with variation in wood species towards flexural properties of Glulam beam. Experimental study have been done by using local wood Sengon and Rajumas as laminae and Biomatex as adhesive, at 0.6 MPa of clamp pressure. The variation of finger joint slope was tested are 1:8; 1:12; and 1:16. The result show that the glulam Sengon and Rajumas beam with slope finger joint of 1 over 12 produce the highest average bending strength of 299 kg/cm 2 and 318 kg/cm 2 respectively. The flexural strength of glulam Rajumas was 20% higher compared with glulam Sengon.
