Assumethat only rotation of joints occur at B, C and D,and that no support displacements occur at B, Cand D. Due to the applied loads in spans AB, BCand CD, rotations occur at B, C and D.150 kN15 kN/m10 kN/m3 mADBCIII8 m6 m8 m4In order to solve the problem in a successivelyapproximating manner, it can be visualized to bemade up of a continued two-stage problems viz.,that of locking and releasing the joints in acontinuous sequence.7.2.1 Step IThe joints B, C and D are locked in positionbefore any load is applied on the beam ABCD thengiven loads are applied on the beam.
