Fig. F$-1$: A plane $(2$D$)$ frame

Note: the frame material is: Concrete AS$3600(1994)-$Compressive Strength $f^{\text{'}}c=25$MPa $($you will get it in Strand$7).$ For simplicity, treat the member sections un$-$cracked and ignore any effect of reinforcement.

The floor level beams are subjected $12\mathrm{.}5k\frac{N}{m}$ uniformly distributed gravity loads while the roof level beams are subjected $8k\frac{N}{m}$ uniformly distributed gravity loads. Treat the gravity loads and lateral $($horizontal$)$ loads as separate load cases.

The size of the members are: floor level beams $-250mm400mm($depth$)$; roof level beams: $250mm300mm($depth$)$; columns $-450mm450mm.$

Use the right "Freedom Case" under "Global" to have $3$ DOF per node.
