A three-hinged parabolic arch of total span 30 m has its two end supports at 4 m and 16 m below the crown respectively. The arch carries two concentrated loads, each of 60 kN in the middle of each portion of the arch on both sides of the crown as shown in the figure. Determine the horizontal thrust and vertical components of the reactions at supports. Also determine the bending moments acting under the concentrated loads. 60 kN 30 m 60 KN E B 16 m

The roof deck of the single story building is subjected to a dead load plus live load of 45 kN/m^2. If the purlins are spaced 1.5 m and the bents are spaced 6 m apart, determine the distributed loading in kN/m that acts along the purlin Dl. m 6 m toute H m 7 @ 1.5 m = 10.5 m

The simply supported bending moment at the central hinge of a three hinged arch is 36 kN-m. The span and rise at the hinge are 12 m and 3 m respectively. The horizontal thrust in the arch is?
