2 Jordan Overview of Reinforced Steel Steel is an alloy of iron with carbon and usually other elements. Reinforced steel also known as rebar, is a steel bar or mesh of steel wires. Rebar is used as a tension device in reinforced concrete and masonry structures. The rebar strengthens and is able to hold the concrete in compression. The surface of rebar is usually patterned in order to form a better bond with the concrete. Before rebar, concrete structures were not reinforced. The use of rebar started in the 15 th century. Human Needs, Human Wants, Human Expectations Humans need strong reliable structures that can withstand the forces of nature. We need rebar to reinforce concrete and make it stronger. Reinforced concrete is used for slabs, walls, beams, columns, foundation, frames and more.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
