The most common method of bridge erection is the cantilever type, in which the structure is built out from the piers across the span. Metal spans are assembled by a crane that moves along the finished portion; the bridge elements move under the crane along a track on the assembled span. ...
Although wooden bridges were common at first, stone bridges (especially arch bridges) increasingly dominated until the Middle Ages; as Palladio said: “Stone bridges were built for their longer life, and to glorify their builder” (Palladio, 1570). One of the most incredible periods of bridge ...
1. A load bearing support structure comprising: at least one modular structural section; and support means having a surface having a predetermined contoured shape for supporting said at least one modular structural section, said at least one modular structural section comprising: at least one beam,...
the structure comprises a plurality of piers bearing on the foundations, the cross-beam bearing on said plurality of piers, and the reinforcement apparatus comprises, for each pier the cross-beam is bearing on, a column destined to surround said pier at least partly, to be mechanically coupled...
(a temporary structure to impound the water)must be built or the water must be diverted into another channel or area down-stream from the dam site. For large projects, this construction may be done several seasons before building of the dam begins. The flow of water is closed off at the...
Some structures like the Summerblue Arts Camp stage shown in our photo should be built deliberately sloped in one direction. We might slope the surface of a deck slightly, perhaps 1/8" per foot, to improve drainage and to send its drainage away from the building to which its attached. In...
arrangement at intervals up the height of the formwork members14,16. The vertical reinforcing bars58are anchored in a wall support (not shown) on which the wall is built. This considerably enhances the strength of the wall assembly by bracing the components of the wall securely to the wall ...
They also cause less seabed damage, as additional slackness can be built into the mooring system. However, these mooring systems are principally designed to prevent drift of vessels and are not designed to provide low scope, small footprint performance in deeper waters. These current elastomeric ...

A turbulent boundary layer is visible on both the upper and lower walls, and large turbulent structures of increased brightness are present, which penetrate into the core flow. The physical mechanism responsible for the increased light scattering in these regions is discussed in Section 3.7 below. ...
