Q$1$

a$)$ For a frame under lateral load discuss when the use of the portal and the cantilever

methods are more appropriate.

b$)$ The frame shown undergoes elastic deformation under the applied loading.

$($i$)$ State if the frame is determinate or statically indeterminate and to what degree.

$($ii$)$ Use approximate methods to solve for the shear and moment in the beam DE due

to the gravity load.

$($iii$)$ Use the portal method to solve for the shear and moment in the beam DE and the

axial force and moment in the column AD due to the lateral load.

$($Hint: Transpose respective loads along local axis of members$)$
