Design Example of A Deep Beam Using Strut$-$and$-$Tie Method per ACI $318-02$ Appendix A

Consider the $2$ meter deep beam described in Figure $1$ below. Use the strut$-$and$-$tie model to determine the required amount of reinforcement.

Additional details: $f_c^{\text{'}}=30$MPa,$f_y=400$MPa,$P_{DL}=800kN,$ and $P_{IL}=400kN.$
