Flexure behavior of a hybrid reinforced concrete beam. Strain correlation between mechanical gauges and optical measurement

Civil engineering is a professional engineering field that deals with the design, construction, and maintenance of the physical and naturally built environment. There are several disciplines that can apply in civil engineering like mathematics and physics. Failure in flexure will occur when the bending moment is sufficient to induce tensile stresses greater than the yield stress of the material throughout the entire cross-section. In structural analysis, this bending failure is called a plastic hinge, since the full load carrying ability of the structural element is not reached until the full cross-section is past the yield stress. In order to prevent the failure of a reinforced concrete element at bending moment it is important to know the maximum bending moment capable to sustain the force being placed. Experimental methods are used specifically for elements with irregular form. Therefore obtaining the bending moment resistance, for a hybrid beam, by experimental methods is a more accurate method.
