Today the construction of bridges has gained worldwide importance. Bridges are an important feature of all road networks and the use of pre-stressed bridges is increasingly popular in the construction of bridges due to their better stability, service friendliness, economy and durability, beauty and appearance of the building. Reinforced concrete construction, steel or steel construction using composite construction. In the case of high spaces, reinforced concrete construction makes no money due to the large space. cross-section is used more effectively than cross-section of reinforced concrete. Prefabricated concrete is used for long bridges with a length of more than 10 meters. Typically, when bridges are calculated, the superstructure and substructure are analyzed separately. The supernatural structure is usually a grid made of large strips, a shortcut membrane and a desk slab. vertical grid Columns of large girders with anchors. The superstructure is tested according to IRC: 62014 and according to IRC: 182000 with unimaginable gravity loads and loads of moving vehicles. Reduced stress and deviation rates compared to a straightforward tender profile.
