Abstract
The tropical forests that are spread throughout Indonesia territory support the processes for constructing the wood bridge. However, the availability of camphor wood with adequate capacity is very limited. The planning of composite beams for laminated wood bridges and reinforced concrete is expected can receive higher loads. Laminated wood is planned by using anchors in the beam support area. In addition, external reinforcement in the form of Carbon Fiber Reinforced Polymer (CFRP) is applied to the tensile section of the composite beam. Variations in the CFRP layer on the tensile section of the composite beam affect the beam^s ability to carry loads. Experiments were carried out with Displacement Control using One Point Load on the beam. The beam is loaded with a static (monotonic) load with a constant ramp actuator speed of 0, 05 mm/s until the beam collapses. The test results showed that the laminated concrete-reinforced composite beam using 3-layer CFRP reinforcement could carry a load 34% greater (70.29 kN) than the composite beam without CFRP reinforcement (52.53 kN)
