Abstract
This study investigates the influence of tendon diameter and slab depth on the shear capacity of prestressed hollow-core concrete slabs, utilizing Concise Beam software for parametric analysis. Prestressed concrete slabs are widely used in construction due to their efficiency, but understanding the interaction between tendon configuration and slab depth is crucial for optimizing shear strength. The research models various tendon diameters and slab depths to assess their effects on shear capacity under typical loading conditions. Through simulations conducted in Concise Beam, the study quantifies how changes in tendon diameter and slab depth influence shear resistance, providing insight into the optimal configurations for enhanced performance. The results are presented through comparative analysis, revealing key trends and offering practical recommendations for engineers to improve the durability and safety of prestressed hollow-core slab designs. The study demonstrates the effectiveness of Concise Beam in evaluating shear capacity and optimizing prestressed concrete slab configurations for both strength and material efficiency.
