Types of bridges

 Reinforced bridges

They are made of steel subjected to tensile and compressive stresses. No bending moment is allowed in this structure. The most stable structural form is triangular.

Arch type bridges

The arch bridge is mainly subjected to compressive stresses. It uses an aerodynamic system with torsional stiffness.

Suspension bridges

In the suspension bridge type, long spans can be provided. It gives a lot of freedom to the design engineer to provide a long span with the help of tensioning cables. It mainly consists of the following:

Slab-type bridges

This is the most common type of bridge. Used almost everywhere where the span is not so long.

Box girder bridges

It is a box girder different from the normal "I" girder, it can easily resist an amount of torsion. This type of bridge contains an upper deck, vertical web and bottom slab.

Reinforced and reinforced concrete

 One development that may result in the rehabilitation of arch bridges is the use of reinforced concrete. The material to be used for this is somewhat complex, because it has been found that concrete alone is not strong enough for tension, although it is admirable for compression. The reinforced and reinforced concrete to be used consists of a solid mass, which surrounds a skeleton or steel reinforcement suitably arranged and arranged to resist the forces that are to act upon it. The longitudinal steel bars are placed in the reinforced concrete pieces on the edge that must resist the traction; the rectangular pieces are the stirrups that resist the shear forces. Longitudinal pieces are placed on the compressed edge to facilitate the assembly of the reinforcement. The first reinforced concrete bridge Traditionally, JOSEPH MONIER has been regarded as the discoverer of reinforced concrete. MONIER was a gardener by profession and in 1867 he issued his first patent for the manufacture o...

To find the oldest bridge ever built in the history of mankind, it is necessary to go back to the period of the maximum splendor of the Babylonian civilization, during the reign of Nebuchadnezzar, who ordered the construction of a bridge over the Euphrates River to permanently connect the various districts of the city of Babylon, which were separated by the course of the river. This bridge, according to the testimony of Greek historians, was more than 900 m long, a figure that also indicates the width of the river at that point, and had 100 stone pillars supporting a platform, built of palm beams closely linked together with lianas and covered by a roof. The large number of pillars and the small distance between them, about 5 m, resulted in a notable irregularity in the flow of the river waters, frequently causing obstructions and flooding in times of flood. Only some time later, in Mesopotamia, with the adoption of arched openings, it was possible to improve the construction of bridge...

 Did you know that? The Chapel Bridge or Kapellbrücke is a 204-meter long bridge that crosses the Reuss River in the city of Lucerne in Switzerland. It is the oldest wooden covered bridge in Europe; one of the main tourist attractions of this country and one of the most photographed areas. Since the beginning of mankind, man has needed to cross small streams, deep ravines and other physical obstacles. First, to move through the territory in search of food, and then for the need to communicate and interact with their peers. This was the beginning of the history of bridges, which evolved through the centuries and led to the development of structural engineering as we know it today.
