Homework

A rectangular beam is to have a service $M_D$ of $320kN.m($including moment due to beam self weight$)$ and a service $M_l$ of $560kN.m.$ In your design assume the following:

A width of $350mm$ and a depth of $)=350,h=750,d^{\text{'}}=(65(mm)$

Materials of and $fy=420$MPa.

Two layers of longitudinal reinforcement $(d=h-40-10-25-\frac{25}{2}.$

Bar diameter of $25mm$ for longitudinal reinforcement.

Bar diameter of $10mm$ for stirrups.
