PART B
Answer any two full questions, each carries 15 marks.
Analyse the rigid frame ABCD by moment distribution method. Ends A and D are
fixed. AB and CD are vertical members with moment of inertia I and length 4m. The
horizontal member BC with moment of inertia 21 is 6m long and acted upon by a

concentrated load of 1001:1 3+ 2m from 8.

Analyse the three-span continuous beam ABCD by Kani’s method and draw BMD
and SFD. Left end support A is fixed and all other supports are roller supports. Span
AB=6m, BC=5m and CD=4m. Span AB carries a central concentrated load of 80kN,
BC carries a concentrated load of 80 kN at 2m from B and CD carries a UDL of

30kN/m. EI is constant.

a) Determine the moments at A, B, C of frame shown in Fig. 2 using Kani’s method

and plot BMD.
