This course ‘Design of Reinforced Concrete Beam’ gives you detailed understanding, explanations and procedures for the design of RC Beams. 8 A singly-reinforced concrete beam 350 mm wide and 550mm deep to the centre of the tensile reinforcement is reinforced with 3 bars of 18 mm diameter. Analytical calculations are correspondingly. Design for shear and deflection. This is a detailed example problem that describes the process for calculating the design moment strength of a singly reinforced concrete beam according the ACI Code. Factors to be considered are the basic span/depth. you can strengthen a reinforced concrete beam by application of a steel plate/frp up to a point where the area in the stress block under compression is at a max.
