A three hinged parabolic arch hinged at the crown and springings, has a horizontal span of 4.8 m and a central rise of 1 m. It carries a uniformly distributed load of 0.75 tonne per metre over half left hand span. The horizontal thrust at the support will be

Support reactions Va and Vb will be 1.35 and 0.45. Then apply equilibrium equation at crown.

convert distributed load to point load for easy calculations = 0.75*2.4=1.8 acts in the middle of left hand side.
Take moment at c = 0. Vay and Vby are 1.35 and 0.45.
Then take moment at crown is zero. Vax = 1.08 tonnes.
Take moment at c = 0. Vay and Vby are 1.35 and 0.45.
Then take moment at crown is zero. Vax = 1.08 tonnes.

Due to the u.d.l the reactions at the supports are Ra=1.35&Rb=0.45.
Take the left half or right half of the arch. Take the moments about hinge C.
There fore £Mc=Vb*2.4 - H*Y = 0.
0.45*2.4-H*1 = 0.
H= 1.08 tonnes.

Guys take it simple,
H = wl2/16h.
H = 1.08 tonnes.
H = wl2/16h.
H = 1.08 tonnes.

H = 2Pl^2/8h.
H = 1.08 tonnes.
H = 1.08 tonnes.

H = (wl^2/16h).
W-UDL over the left or right portion of the arch.
h-Central rise.
L-horizontal length.
Ans - 1.08t.
