Development length design

A rectangular beam has $b=350mm$ and $d=450mm.$ The beam is simply supported over a length of $5m$ measured from the center of the support and is reinforced for tension with $7$ of $20mm$ diameter bars. Assuming $f{c}^{\text{'}}=27$MPa, fy $=345$MPa, draw the details of the bar showing the cut off points of each bar. The beam carries a uniformly distributed load throughout its length and is made up of normal sand$-$gravel concrete. The reactions at the ends produces compression on concrete. Maximum value of $I_a$ is $150mm.Vu=150kN$ at support.

Hint : extend $3$ bars beyond the support
