There are three structural design methods, namely, working stress, limit state, and final load method of structural design. These design methods are used both for reinforced concrete and for the design of steel structures. Concrete Structure Design Methods A structure refers to a system of connected parts that are used to support forces (loads). Buildings, bridges and towers are examples of structures in civil engineering.
In buildings, the structure consists of walls, floors, roofs and foundations. In bridges, the structure is composed of roof, support systems and foundations. In towers, the structure consists of vertical, horizontal and diagonal members together with the foundations. For a strong, ductile and durable construction, the reinforcement must have high strength, high tensile stress, and good adhesion to concrete and thermal compatibility.
Building components such as slab walls, beams, foundation pillars & frames are built with reinforced concrete. Recently, a large number of additives known as concrete additives have also been added to improve the quality of concrete. These elements are “reinforced concrete”, concrete can be cast into any complex shape using suitable formwork and has high durability, better appearance, fire resistance and economical. Concrete design methods or concrete design philosophies such as the work effort method, the maximum strength method, and the limit state method are used for the design of reinforced concrete, steel, and wood structures. Concrete repair is an important part of maintaining any Concrete structure and should be conducted by a qualified professional.
