Beams subjected to simple bending- Rectangular section and T

Abstract

Beams are structural elements that are scaled to support the requests that are submitted. It is often used, especially in Brazil, the construction method of beams in reinforced concrete, this type of structure consists in the use of frames made with steel bars and covered in concrete. The individual concrete has high compressive strength and low tensile strength, so the steel, with high tensile strength, used in beams and other reinforced concrete structures, acts fighting tensile stresses and the two materials must work as a monolithic set. The method for sizing beams subjected to simple bending for rectangular sections and T or L sections is shown in a practical example. The method proved to be efficient and the results of the sizing of the beams were satisfactory.
