Laminated bamboo can be used as an alternative elements of building materials. Laminates techniques can be used to form the building materials used as construction in large sizes. Previous studies have extensively covered the beam strength of laminated bamboo, type and crack. The test of the shear strength with the use of 60 MDGL A (Mutilayer Double Glue Line), resulting in shear fracture between bamboo material and not occur in the adhesive. Comparison between high beam size and the width is 120 mm x 60 mm. Further tested the strength of the beam to the shear capacity with four variations of adhesive. Using bamboo outer skin on the surface of the beam and the use of 50 MDGL adhesive variations. The results showed that there was no significant difference in shear strengths between the variations of each adhesive . Beam strength is highest test object is on 50 MDGL C with a value of 24.4 KN load with a deflection of 41.5 mm. The average shear stress laminated beams obtained is on 5.49-6.66 and 4.58 MPa. This strength is still greater than the strength of the wood beams in general, where the wood shear stress is 1.25 MPa class II.
