Analyse the frame below using the moment distribution method. Support A settles by 15 mm and differential temperature is acting on the members AC. Consider E= 210 GPa for all members, IAC = IEDF = 5 x 10 mm, laco = 1.5 lac and coefficient of thermal expansion, a = 11.7 x 10-6/C. 1) Determine fixed end moments. (7) 2) Determine end moments.
