Abstract
This study investigates the impact of tendon diameter and slab depth on the deflection behavior of prestressed hollow-core concrete slabs, utilizing Concise Beam software for parametric analysis. Deflection is a critical factor in the serviceability of prestressed concrete slabs, and understanding how tendon configuration and slab depth influence deflection can aid in optimizing design for both strength and performance. Various tendon diameters and slab depths are modeled in Concise Beam to evaluate their effects on slab deflection under typical loading conditions. The analysis reveals how changes in tendon diameter and slab depth influence deflection patterns, providing key insights into deflection control. The results are presented through graphical comparisons, offering practical recommendations for engineers to design slabs that meet serviceability requirements while optimizing material use. The study demonstrates the efficiency of Concise Beam in evaluating deflection behavior and highlights the importance of tendon and depth configurations in prestressed hollow-core slab design.
