INVESTIGATION OF THE TENSILE STRENGTHS AND DUCTILITY OF REINFORCING STEEL USED IN COLLAPSED BUILDING PROJECTS IN SOUTH EAST NIGERIA

Abstract: This research work assessed the tensile strength and ductility of reinforcing steel bars used in the construction of collapsed building projects in South East, Nigeria. The method adopted in the work was laboratory experimentation and testing of the tensile strength and ductility of the reinforcing steel bars. The results obtained revealed that fifteen percent (15%) of the reinforcing steel bars used in the collapsed buildings under study, were of good quality another fifteen percent (15%) were of satisfactory quality, while seventy percent (70%) were poor quality reinforcing steel bars. On the other hand, fifty five percent (55%) of the reinforcing steel were ductile, while forty five percent (45%) of them, were brittle in nature. Thus a substantial quantity of reinforcing steel bars available in building material market in South East, Nigeria, are both weak and brittle in nature. This implies that there is a high probability that any steel acquired and deployed for construction of buildings, may be sub-standard. It is therefore, recommended that all reinforcing steel bars must be tested to determine their quality and hence their suitability for building construction Keywords: Tensile strength, Ductility, Reinforcing steel, Concrete and Collapsed Building Structures.
