Template For An Inspection Report On A Building

bridges have their origin in the same prehistory. Possibly the first bridge of the story was a tree that prehistoric man used to connect the two banks of a river. They also used stone slabs for streams or small when there were no trees nearby. The following bridges were bows made of logs or planks and eventually stones, using a simple bracket and placing cross beams. Most of these early bridges were very poorly constructed and rarely bear heavy loads. It was this failure that led to the development of better bridges. The arch was first used by the Roman Empire for bridges and aqueducts , some of which still stand today. Based bridges could stand arches conditions that would previously have been taken ahead of any bridge.
A bridge is a construction, usually artificial, that saves a geographical or other physical constraints such as a river a barrel a Valley, a road a railway a waterbody , or any obstruction. The design of each bridge varies depending on their function and nature of the land on which the bridge is built.
Your project and its calculation belong to the structural engineering , with many types of designs that have been applied throughout history, influenced by the available materials, techniques developed and economic considerations, among other factors.
A bridge is designed to train, car or pedestrian traffic, gas or water pipes for transportation or shipping. In some cases there may be restrictions on its use. For example, can be a bridge on a highway and prohibited for pedestrians and bicycles, or a pedestrian bridge, possibly also for bicycles.
The area under the many bridges have become makeshift shelters and shelters for the homeless.
The undersides of bridges all over the world are frequent points of grafiti .
A aqueduct is a bridge that carries water, resembling a viaduct , Which is a bridge connecting points of similar height. Materials

different materials are used in the construction of bridges. In ancient times, was used mostly wood and stone was used subsequently. More recently built metal bridges, material that gives them more harshly.

The main materials used for building the bridges are

· Stone
· Wood
· Steel
· Reinforced (concrete)
· Prestressed concrete
· post-tensioned concrete
· Mixed
