EXPERIMENTAL STUDY ON FLEXURAL BEHAVIOR OF RED MERANTI (SHOREA SPP.) GLULAM BEAM OF VARIOUS NUMBER OF LAMINAE

This research aims to study flexural behavior of Red Meranti (Shorea spp.) glulam beam of various number of laminae by carrying out testing beams made from four, six, and eight laminae. Four points bending test method according to ASTM 198-22 was applied. The research results show that glulam composed of a smaller number of laminas reaches a smaller flexural rigidity. The empirical equations for flexural strength ratio and modulus of rupture ratio, and the trend of flexural rigidity between glulam and solid proposed in this study can be used in designing the flexural members of timber buildings, timber bridges, and in calculating the deflection of timber beams.
