A symmetrical two-hinged parabolic arch rib has a span of 48 m between the abutment pins at the same level and a central rise of 10 m. Moment of inertia at any section follows the law I=I0secθ. If a load of 80 kN crosses the span then maximum horizontal thrust at the hinges will be ______ kN.131.25 |
