Evaluation of RCC building performance with stainless steel hysd reinforcements replacing conventional HYDS steel

The objective of this investigation is to evaluate and contrast the performance of solid concrete (RC) structures that are reinforced with brushed stainless steel HYSD and common HYSD steel reinforcements. The study focuses on how corrosion impacts building durability and maintenance, and it investigates the viability of stainless steel as an option owing to its greater corrosion resistance, mechanical strength, and durability. ETABS software was used to assess RCC building models of varied heights (G+2, G+5, G+8) under various loading conditions, including seismic forces, in accordance with IS:1893:2016 requirements. Tensile and torsion tests on HYSD550 and SS550 reinforcement bars were carried out to confirm the computational results. The results show that stainless steel reinforcements provide comparable structural performance to conventional reinforcements, with the additional benefits of increased ductility, longer service life, and lower maintenance costs. This study shows stainless steel as a sustainable reinforcement material for important infrastructure, particularly in harsh conditions.
