e design of different structures is done by performing two main steps. The first is determining the different forces acting on the structure using proper methods of structural analysis. The second is proportioning all structural members economically. The safety, stability, serviceability, and functionality of the structure all have to be thought about. Structural concrete is one of the materials commonly used to design all types of buildings. It is made up of two component materials. These are concrete and steel. They work together to form structural members that can resist many types of loadings. The key to its performance lies in strengths that complement each other. Concrete resists compression. Steel reinforcement resists tension forces. 2. The term structural concrete indicates all types of concrete used in structural applications. Structural concrete may be plain, reinforced, prestressed, or partially prestressed concrete; in addition, concrete is used in composite design. Composite design is used for any structural member, such as beams or columns. long dashHassoun, M. Nadim. Structural Concretelong dashTheory and Design. Wiley, 1998.
