There are several researchers have examined laminated bamboo beams. The outcomes revealed that laminated bamboo beams had high flexural strength but low elastic modulus. The low modulus of elasticity causes the beam to have low stiffness so that the high flexural strength cannot be utilized optimally. This study seeks to analyze the increasing amount of beam stiffness by adding CFRP along the tensile and or compressive sections of the beam. To get the result, a numerical simulation was carried out on laminated bamboo beams with a cross-sectional of 50 mm in width, 50 mm in height, and a span length of 1,400 mm. There are three groups of beam treatment, the name given for CFRP in both tension and compression zones, in the compression zone, and in the tension zone. The length of CFRP for the three treatments is the same as the span of the beam. The results of the numerical analysis showed that the beam with the addition of CFRP experienced a significant increase in stiffness. Compared to the stiffness of the beam without CFRP, the beam with the addition of CFRP in both the tension and compression zones, in the compression zone, and the tension zone, experienced an increase in stiffness of 66.21%, 51.19%, and 15.89%, respectively. The model of damage to the beam is divided into flexural damage and shear damage. The simulation results indicate that the beam with the accumulation of CFRP in both tension and compression zones encountered flexural damage and shear damage; the beam with the addition of CFRP in the compression zone underwent flexural damage, and the beam with the addition of CFRP in the tensile zone experienced flexural damage and shear damage. © 2024 American Institute of Physics Inc..
