$[$Total: $25$ Marks$]$

Design Data: Refer to the drawings of a Typical Floor Plan and Cross Section shown in the Figure below:

Building use: Office

Location: Hamilton

Design working life: $50$ year

Site Subsoil: Shallow soil

Ductility: $=2$

Distance to nearest major fault: $15km$

Lateral load resisting system: Steel moment resisting frames.

Permanent load on each floor $($level $1$ and roof$)$ including columns, beams, floors, cladding and SDL $=2\mathrm{.}5$ kPa $.$

The rigidity of all transverse frames along axes $A,B,C,D,$ and $E$ is equal $($i$.$e$.$

$($:$R_A=R_B=R_C=R_D=R_E$
