ABSTRACT

Deep beams provide a high load support capacity based on the building function. Although deep beams perform better than ordinary beams, shears due to overstress cause failure before moment capacity achievement. The behavior of geopolymer concrete as a material with a compressive strength equal to or higher than conventional concrete shows its potential as a material for structural members. Studies about structural members using geopolymer concrete as materials are still needed to explain the deep beam performance adequately. The purpose of this study was to analyze the shear capacity of geopolymer concrete deep beams, which has a ratio variation of transverse reinforcement ratio to monotonic loads. The analysis was performed using software based on the finite element method. The objectives of the analysis were to determine the performance of deep beams from load-deflection curves, ductility ratio, stress contours, deflection contours, stiffness, dissipation energy, and shear. The geopolymer concrete deep beam with a transverse reinforcement ratio of 0.25% could withstand the highest loads. The beam also experienced the lowest deflection compared to other beams with less shear reinforcement ratios under the same load. It also achieved better dissipation energy, ductility ratio, and shear capacity than the normal concrete counterparts.
