<![CDATA[The aimed of this research was to determine the flexural behavior of glulam beam made from pine wood (Pinus merkusii) under various laminate thicknesses and then compared to its solid beam. The material used was pine wood with moisture content of 10% and and polyurethane adhesive (Water based polymer isocyanate, WBPI). Four types of glulam beams (namely, Glulam A, B, C, and D) produced with laminate thickness of 25, 16.67, 12.5, and 10 mm, respectively. Solid beam was also prepared as control. All beams have a cross sectional dimension of (50x50) mm2. Bending test is conducted using a 5 ton capacity of Universal Testing Machine, Instron 330. The results indicated that incerasing in number of laminate to a point tend to increase the values of stiffness and modulus of rupture (MOR) of glulam beams. However, the higher of laminate thickness tends to decrease the stiffness and MOR values. Energy absorption of solid beam was noted twice compared to glulam beams.Key words: flexural behavior, glulam beam, modulus of rupture, Pinus merkusii, stiffness]]>
