PART C
Answer any two full questions, each carries 20 marks.
Determine the shape factor of T- Section with flange width 120 mm. Depth of web is
110 mm. Thickness of flange and web is 10 mm. If the value of yield stress is 250
N/mm, find the plastic moment capacity of the section

Determine the deflection at free end of a beam in the shape of a quadrant of a circle

in plan, fixed at one end and free at the other, with a point load at the free end.

Derive the expressions for bending moment and twisting moment at any section in a

circular ring beam supported by a no: of columns placed at regular intervals.

Determine the value of collapse load for the portal frame shown in Fig 4. All the

members have the same plastic moment of resistance.
