Beam bridges are generally considered the simplest form of bridge. Because both of the arch’s ends are fixed, the horizontal forces that are placed on it, like that from driving, are displaced equally. There are multiple design options from which to choose. One of the most famous bridges of this type is the Sydney Harbour Bridge in Australia, which is based on the Hell Gate Bridge in New York City. A comparative analysis with other types of hanger arrangements is also performed. A wide bridge may require an arch so tall as to become a significant obstacle and incline for the roadway. The use of a through arch does not change the proportions or size of the arch: a large span will still require a tall arch, although this can now reach any height above the deck without obstructing traffic. Deck arch bridge – Common arch bridge in which deck is situated on top of the arch. In some cases, this type of arch has been created by constructing cantilevers from each side, with the shoreside ends bolted securely down into heavy piers.

In some cases, this type of arch has been created by constructing cantilevers from each side, with the shoreside ends bolted securely down into heavy piers. As well as tying the side-loads of the arch, the tension member is also at a convenient height to form the bridge deck, as for a through-arch. In particular, cast iron bridges such as the Stanley Ferry Aqueduct may resemble tied-arch bridges, but as cast iron is weak in tension they are not structurally a tied arch. In this through arch bridge design example, the admissible design domain, boundary conditions, and load conditions are shown in Figure 9.The design domain is modeled into elements, a uniform load is applied in the bottom of the design domain, and the prescribed volume fraction is .
