The deep beam shown below is to be designed using the strut and tie method using the virtual truss geometry and forces $($in $kN)$ shown $($dashed members are in compression, solid members are in tension$).f^{\text{'}}c=32$MPa.

Calculate the area of reinforcing steel required for each tie.

Calculate the minimum width of the $6$ struts at node B$.$

Draw the node shape for node B $($to scale with a ruler$)$ and calculate the minimum face dimensions for node B such that it is hydrostatic.

Show that node $B$ has adequate capacity $($you can ignore eccentricity of the forces acting at node $B).$

beam depth $($into the page$)$ is $800mm$
