ABSTRACT
This project work titled " Experimental Investigation of The Tensile Strength Of 16mm Reinforcement Steel Rods (A Case Study in Benin City, Nigeria)" aims to investigate the tensile strength of 16mm reinforcement steel rods in the unique environmental context of Benin City, Nigeria. The research design adopted an experimental approach to investigate how various factors influence tensile strength, with data collected from a representative sample of steel rods.
The research methodology included sample selection, preparation, and tensile testing under controlled conditions. Data analysis incorporated descriptive and inferential statistical techniques, providing insights into factors affecting tensile strength. The findings revealed significant variations in tensile strength attributable to factors such as the manufacturer, surface conditions, and environmental parameters.
Steel rods are used every day in different construction sites in Benin city but their suitability is still not confirmed. This therefore prompted the researcher in selecting 14 samples of T16 strength analysis. It was observed that none of the selected samples meet the nominal diameter criteria as average diameters were ranging from 15.75 – 15.80mm for T16. Average values of yield strength were 431 N/mm2 as against 460 N/mm2 dictated by the BS8110 and BS4449. Percentage elongation was6% for T16 which was not up to the standard percentage elongation (10-14%). It was therefore recommended that the appropriate authorities shouldenforce the laws guiding production and distribution of reinforcement in the country for optimum safety.
These results emphasize the critical importance of considering regional and environmental factors when selecting reinforcement steel for construction projects in specific locales. Additionally, the ethical conduct of the research was upheld throughout, ensuring integrity and credibility. The study provides a valuable contribution to the construction industry, enabling engineers and stakeholders to make informed decisions regarding the use of 16mm reinforcement steel rods in Benin City. It is anticipated that these findings will drive the development of safer and more resilient structures in the region and beyond.
