Abstract

Indonesia has a lot of abundant material resources. One of them is the availability of solid wood that can be used for bridge construction. The wood used as a bridge structural element has a 15-20 meters span with class III road loading capacity. However, wood has limited dimensions. Therefore, it is needed for wood to be composited into reinforced concrete laminated beams as planned. The planning of reinforced concrete laminated wood beams refers to the materials’ characteristics, including the mechanical properties of Camphor wood. These characteristics are used as the basis for analyzing the performance of Laminated-concrete-reinforced Camphor composite beams. The dimensions of the composite beam specimen are 250 x 30 x 25.5 cm in the scale of a 1:3 model with actual measurements. The analysis was carried out manually to determine the strength of the Laminated-concrete-reinforced Camphor composite beams. The variables used in this analysis include the number of layers of CFRP as flexural reinforcement compared to beams without CFRP reinforcement. The number of layers of CFRP consists of 1 layer, 2 layers, 3 layers. Composite beams were analyzed with two concentrated loads in the area 1/3 of the span length from the supports. The results of the analysis show that the composite beam using CFRP can carry an additional load of 86.86 kN (101.68%) for 1 layer of CFRP; 87.99 kN (103.07%) for 2 layers of CFRP; and 93.81 kN (109.83%) for 3 layers of CFRP compared to the experimental load that can be received by standard composite beams of 85.42 kN (100%).
