This paper was intended to describe the performance of mix-glue laminated timber beams (mix-glulam) compose of coconut wood (Cocos nucifera) and sengon wood (Albizia falcatara) in the outer zone and core zone, respectively. Mix-glulam system is an alternative to utilizing a low-grade timber as structural member of building. Through the analysis of four-point-bending-test results of each of five mix-glulam beams (BLG) and five sengon-solid beams (SDL) with span (L) = 2750 mm, height (d) = 155 mm and width (b) = 55 mm was obtained that the mix-glulam system produces a good performance. The analysis result showed that the flexural rigidity (EI) of BLG is 1.66 times higher than SDL. Likewise, the maximum bending stress (σmax) of BLG is 1.6 times higher than the σmax of SDL with tension failure in bending. Generally, the failure of the beam that occurs is a brittle and sudden tension failure. © IAEME Publication.
