A reinforced concrete beam has a simple span of 8m

A reinforced concrete beam has a simple span of 8m. It carries a concentrated service load, P=200kN(40%DL and 60%LL), at midspan. The 300mmx400mm beam is reinforced with 3D25mm and 12mm stirrups. Take fc’ to be 24.50MPa fy=420MPa and fyt=280MPa. Use simplified calculation of Vc. What is the ultimate shear capacity of concrete at a section 2m from the support, kN? What should be the shear capacity of web reinforcement at the section 2m from the support, kN? What is the maximum spacing of web reinforcement allowed by the code at the section 2m from the support, mm? What is the required spacing of web reinforcement at the section 2m from the support, mm?
