PROBLEM 1: A reinforced concrete beam has a simple span of 8m. It carries a concentrated factored load, Pu, at midspan. The beam is reinforced with 3D25mm. It has a width of 300mm and an effective depth of 450mm. Neglecting the weight of the beam, and using the exact/detailed calculation for Vc. 1. What is the ultimate shear capacity of concrete at a section 2m from the support? 2. What should be the shear capacity of web reinforcement at the section 2m from the support? 3. What is the maximum spacing of web reinforcement allowed by the code at the section 2m from the support if the diameter of stirrups is 12mm? 4. What is the required spacing of web reinforcement at the section 2m from the support if the diameter of stirrups is 12mm? 5. Draw the design details for shear of the beam from x=Om to x=2m.
