Advantages
Because arch and tie are mainly subject to axial forces, their cross sections can be very small. Usually, transverse bending in the deck is bigger than bending in longitudinal direction. Therefore, a concrete deck that spans between the arches is a good solution for bridges with arch distances that are not too large. The concrete deck has longitudinal prestressing tendons in the arch planes.

Famous quotes containing the word advantages:
“Men hear gladly of the power of blood or race. Every body likes to know that his advantages cannot be attributed to air, soil, sea, or to local wealth, as mines and quarries, nor to laws and traditions, nor to fortune, but to superior brain, as it makes the praise more personal to him.”
—Ralph Waldo Emerson (1803–1882)
“To say that a man is your Friend, means commonly no more than this, that he is not your enemy. Most contemplate only what would be the accidental and trifling advantages of Friendship, as that the Friend can assist in time of need by his substance, or his influence, or his counsel.... Even the utmost goodwill and harmony and practical kindness are not sufficient for Friendship, for Friends do not live in harmony merely, as some say, but in melody.”
—Henry David Thoreau (1817–1862)
“We work harder than ever, and I cannot see the advantages in cooperative living.”
—Lydia Arnold, U.S. commune supervisor (of the North American Phalanx, Red Bank, New Jersey, 1843- 1855)
