A two-hinged parabolic arch of span 100 m and rise 20 m carries a central concentrated load of 100 kN. The moment of inertia of any section is I, sec 0, where e is the slope at the section and I, is the moment of inertia at the crown. Compute the reactions at support by the strain energy method. Neglect the effect of rib shortening.
