This set of Structural Analysis Assessment Questions and Answers focuses on “Analysis of Frames : Sidesway-II”.

AB = 12m, BC = 15m, CD = 18m

Load of 40 kN is acting at joint B as shown.

EI is constant throughout the frame.

All force options are given in KN and all moment options are given in KN-M.

FEM represent fixed end moments.
