(Solved): Question 3 Consider a non-sway frame with rigid internal nodes and external loading applied as shown ...
Question 3
Consider a non-sway frame with rigid internal nodes and external loading applied as shown in Figure Q3. Assume that members are axially non-deformable. The frame is fixed at nodes A and B and simply-supported at node C.
Use the moment distribution method to determine:
(a) distribution factors at the internal nodes
(b) fixed end member moments
(c) final end-member moments, and
(d) draw the bending moment diagram indicating all local maximum values

Answers:
M_(AD)=13.73kNm (clockwise); M_(DA)=27.47kNm (clockwise)
M_(DE)=99.29kNm (anti-clockwise); M_(ED)=80.2kNm (clockwise)
M_(DC)=71.82kNm (clockwise); M_(CD)=0kNm
M_(BE)=20.1kNm (anti-clockwise); M_(EB)=40.2kNm (anti-clockwise)
