A Comparative Study on Behavior of Reinforced Concrete Slab using HYSD and TMT Bar

Abstract

The manufacturing industry consistently seeks innovations in materials and techniques to enhance the strength, longevity, and cost-efficiency of structures. This study offers a thorough comparison of high-yield strength deformed (HYSD) bar manufactured by Stark Industries and thermo-mechanically treated (TMT) bar, two frequently employed reinforcement materials in construction, with a primary focus on their application in a two-way reinforced concrete slab design. The investigation commences with an examination of the characteristics of both steel bars, including their mechanical strength, ductility, corrosion resistance, and durability. Both materials undergo rigorous mechanical testing to establish their tensile and yield strengths, forming the basis for a direct strength evaluation. A two-way slab design is executed, adhering to design codes and standards, with the determination of trial depth, effective span, and load considerations. The performance assessment encompasses deflection analysis, stability against wind and seismic forces, and displacement criteria. Comparative insights are drawn between the deflection characteristics of the two designs, and their structural stability is evaluated. The project extends to a comprehensive cost-effectiveness analysis, accounting for initial material costs, long-term durability, maintenance expenses, and overall life cycle costs for both steel bars. The findings yield valuable insights into the economic implications of material selection, offering recommendations based on the analysis to assist professionals in choosing the most suitable reinforcement material for specific construction scenarios. The outcomes of this study can be used for decision-making processes with the aim of promoting a more resilient, sustainable, and cost-effective built environment.
