Abstract

The increased urbanization and consequent requirement for infrastructure accelerate the usage of concrete as a building material. Traditional design practices require large member sizes to meet architectural and structural criteria. As a result, the size of structural parts such as a slab, beam, column, and so on significantly impacts the amount of concrete utilized. The decrease in the self-weight of the structure necessitates optimizing the usage of concrete to lower the structure’s self-weight. The current study investigates using bi-axial voided slabs as an alternative to standard reinforced concrete slabs. A typical bi-axial voided slab eliminates concrete from the center of the floor slab by adding voids, resulting in a considerable reduction in self-weight (around 30–50%). The scientists studied a plate with empty spaces bent in two directions. They also ran experiments. The researcher conducted the numerical analysis using ABAQUS CAE Software to investigate the two-way behavior of a two-way plate with spherical voids. The researcher observes the analytical results of weight and stress for slabs with and without voids. The stress capacity of the two-way slab with bi-axial voids had the same capacity as that of a solid slab. GFRP reinforcement bars replaced the conventional HYSD steel bars. The GFRP bars showed noticeable weight reduction without disturbing the strength of the slab. The voided slab with GFRP as reinforcement showed weight reduction. The residual stresses increased slightly and reached an acceptable value in the slabs where GFRP reinforcement bars were used instead of the conventional HYSD steel bars.
