Abstract
PSWC bar of steel, characterized by its plain surface and wave-type configuration, when used as rebars in concrete construction, has the capability to make concrete constructions durable through several-fold enhancement of life span of such constructions. The use of PSWC bar leads to increased load-carrying capacities of reinforced concrete elements, and it transforms traditionally brittle reinforced concrete into ductile reinforced concrete through several-fold increase in ductility and energy-absorbing capacity of flexural elements of reinforced concrete. All of these have many attendant benefits. It is shown in this article that among rebars of carbon steel, PSWC bar is the most ideal one, as at no added cost or effort, the use of PSWC bar endows reinforced concrete constructions with numerous benefits.
