(1) They are also called  bowstring-arch or bowstring-girder bridge (1) and are part of masonry arch bridges(2).Masonry arch bridges, which have a very long history, and more recent landmark bridges, such as Sydney Harbour Bridge in Australia and the Tyne Bridge in England, are all ‘thrust arches’ and rely on horizontal restraint from the foundations. In many cases, such ‘external’ restraint is not feasible or practical but it can be replaced by a tie between the ends of the arch, thus creating a ‘tied-arch’.

These cables transfer the froces to the foundations of the bridge.

The arch is held longitudinally at one end, with the other end free to expand or contract under varying temperatures. If a load is placed on the deck, it is transferred to the arch via the hangers, as the global stiffness of the arch is greater than the bending stiffness of the deck. This creates thrust in the arch, which is balanced by tension in the tie beam. The arch will deform downwards, and it will try to spread its feet, but this is limited by having to stretch the tie beam. Hence there will be an outward movement at the free end.]]> 2021-05-17 13:06:25 UTC https://padlet.com/deeptisapkota2/37u9stu7qajntg13/wish/1531062948 Main Components deeptisapkota2 https://padlet.com/deeptisapkota2/37u9stu7qajntg13/wish/1531068394 * Good foundation
