1 Determine the horizontal reaction in a semi-circular two hinged arch when a load ‘W’ acts at a point P as shown in figure below. Assume uniform flexural rigidity.
2 (a) Explain in detail about Castigliano’s first theorem.(b) Determine horizontal thrust developed in a semi circular arch of radius “R” subjected to a
concentrated load “W” at the crown.
3 Analyze the portal frame ABCD having supports A and D as fixed. BC & CD portions having anudl of intensity 20 kN/m by using slop deflection method and draw bending moment diagram.Flexural rigidity (EI) is same for all members.
