Experimental Investigation of Yield Strengths of Steel Reinforcing

Having introduced the concrete and steel materials and the design process for good reinforced concrete structural product, it is now necessary to look at the situation on ground in Nigeria Most structures in Nigeria are concrete structures, principally in the form of reinforced concrete frames for buildings, prestressed concrete for bridges and sand Of many fast growing grasses around the world, bamboo has been persistently investigated as a possible reinforcing element in concrete In addition to the existing knowledge on the subject, this study has performed an experimental and numerical analysis of flexural behaviour of largescale bambooreinforced concrete beams Experimental and numerical analysis of largescale bambooreinforced
