Reinforced concrete is the main material in construction in Indonesia, but it has weaknesses in tensile strength and susceptibility to shear failure. This study aims to evaluate the effect of the addition of glass fiber with doses of 0.5%, 1.0%, and 1.5% on the compressive strength, shear capacity, and crack pattern of reinforced concrete blocks. The research method was carried out through laboratory tests on cylindrical and beam test objects, as well as numerical modeling using SAP2000 compared with the provisions of SNI 1726:2019 and SNI 2847:2019. The results showed that the fiber dose of 1.0% provided optimal performance with an increase in compressive strength of 22.4% and a shear capacity of 22.3% compared to normal concrete. In addition, the damage pattern changed from brittle to more ductal with an increase in deflection of up to 18.7%. Modeling validation showed a difference of less than 5% to the experimental data, confirming the reliability of the model used. These findings prove that glass fibers can be an effective alternative to improving structural safety without significant changes to cross-sectional dimensions.
