Arch Bridge


a bridge with span structures, the basic components of which are arches or vaults. Characteristic traits of an arch bridge are the transfer to the supports not only of the vertical but also the horizontal stresses (thrust), as well as the strain, primarily of compression, on the arches or vaults. Stone arch bridges have been known since the most ancient times. Modern arch bridges are built, for the most part, of reinforced concrete or of steel. An example is the railroad arch bridge across the Oka River at the city of Gorky. It was built of precast reinforced concrete and has main spans of 150 m each. In special instances thrustless arch bridges have been erected using special elements (tie beams) which take the thrust. Arch bridges are usually built with a roadway on top. They are marked by lightness of structural components and architectural expressiveness.

The bridge was destroyed in engineering research prompted by national concern about the effects of the increasing weight of traffic on old arch bridges.
In this paper, PLSM which has a lot of geometry information is applied into form finding of arch bridges. The optimization model of minimizing the structural compliance under the volume constraint is proposed.
Moreover, existing codes on arch bridges do not provide any explicit relationships to quantify numerically the dynamic amplification factors involved in stress or displacement variables of the bridge components.

Arch bridges spanning large distances are difficult to build because an arch can't support itself until it's complete.
With the exception of a some brief essays discussing the role of bridges in American transportation, types of bridge design, and the need for bridge preservation programs, the vast bulk of the material consists of 919 captioned illustrations (primarily black and white photographs) depicting beam bridges, arch bridges, truss bridges, movable bridges, and suspension and cable- stayed bridges around the country.
