Abstract

Glulam-concrete composite beams can be a solution for bridge construction with the principle of flexible beams, where the stress must be designed with the upper fibers to withstand the pressure and the lower fibers to withstand the tension. In this case the compressed area is held by the concrete slab, the tensile area is held by wood and the flexural area is reinforced using CFRP (Carbon Fiber Reinforced Polymer) sheets. The experimental study aims to analyze the increase in the value of strength, stiffness and ductility of composite beams by using the number of CFRP sheets as reinforcement in the flexural area of the composite beam. The number of test objects was 4 composite beams consisting of 1 control beam without CFRP reinforcement (BN) and 3 test beams using the total reinforcement of 1 CFRP sheets (BFRP-1), 2 CFRP sheets (BFRP-2) and 3 sheets CFRP (BFRP-3). Flexural testing is carried out with three points of loading using the displacement control method. The test results show that the composite beam BFRP-1, BFRP-2 and BFRP-3 can increase the strength value respectively 3.07%; 9.84%; 1.68%, ductility 72.96%; 38.97%; While the BFRP-1 and BFRP-2 composite beams by 21.28% were able to increase the stiffness by 9.45% and 4.70%, but the BFRP-3 test beam using 3 sheets of CFRP sheets experienced a decrease in stiffness by 16.00%. Composite beams that are reinforced using 1 sheet and 2 sheets of CFRP in the flexural area show better / effective strength, stiffness and ductility than using 3 CFRP sheets.
