I need the solution please. The answers for these questions
are:
HA =63.66kN
Maximum hogging =166.9kNm ( occurs at =32.48 degrees to
horizontal)
Max sagging moment = -327.1kNm at mid span
Point of contraflexure at =64.96
degrees
Question 2 (25 marks) The semi-circular two-pinned arch ABC shown in Figure Q2 is pinned to rigid foundations at Positions A and C. The flexural rigidity (EI) of entire length, and its diameter is 18m. arch rib is constant throughout its The arch supports a single concentrated vertical load of 200KN at its apex (Position B). The self-weight of the arch can be ignored in the analysis. a) Using an energy method of analysis, calculate the magnitude and direction of the horizontal reaction at the support at Position A. (15 marke) Determine the positions and magnitudes of the maximum hogging and sagging bending moments within the arch rib, and the positions any). b) f points of contraflexure (if (10 marks) 1200 kN B 9 m 18 m Figure Q2 One or more the following relationships may be useful: sin 28 2 sin 28 (cos e) 8e -(sin e fcos e sin e 8e contd
