SITUATION $03-$ A rectangular beam has $b=310mm$ and $d=460mm.$ The beam will be designed to carry a service dead load of $230KN-m$ and service live load of $190KN-m.$ Compression reinforcement if necessary will have its centroid $70$ mm from extreme concrete fiber. Use $f{c}^{\text{'}}=30$MPa and fy $=415$MPa. Use reduction factor of $0\mathrm{.}90.$
