Question
Problem-1: Determine the internal moments at fixed supports A and D, and pin supports B and
C of the beam shown in figure below by using moment distribution method. El is constant.
250 kN
20 kN/m
D
-12 m
12 m
4 m'4 m
Solution:
MAR = 62.5 kN – m; M34 = 125.2 kN – m; Mac = -125.2 kN – m; Mca
= 281.5 kN – m; McD = - 281.5 kN – m; Mpc = 234.3 kN – m
