What is the box bridge?
Box Girder Bridge is just one of many bridge styles. It is actually a common style of bridge that has a defecting function in the bridge. The support beams of the box beams are attached together to form a hollow shape of the box. Box beams are sometimes called tubular beams. This hollow box can have the shape of a rectangle, trapezoid or more isosceles triangles that disrupted each other in alternating directions (eg a tip pointing up, pointing down, a tip pointing up). Box beams offer a stronger construction, especially for bridges that must have a curve for them. They are usually used in the highway overpoints. Oakland/San Francisco Bay Bridge is a box bridge. This means that the beams are created in the factory and then bring to the installation bridge. Scriptures can also be made of concrete - prestressed, high -performance or reinforced - OR SCOX BETRONE and steel.
In addition to the beamThe box can be prefabricated and then moved to another location. This is one of the great advantages of this bridge style. It can also be occupied by supporting supports that are removed later or the bridge can be completed in sections. The cranes must be used to move the bridge or part of it. The ability to move the prefabricated bridge to its final placement is ideal for heavy traffic, which can only be closed for a limited time.
While people tend to think of bridges like water, box beams are often found on highways. Many people could ride through the box beam in the form of an overpass on the highway and never noticed. It can also support heavier weights such as light rail transport or lighter operation, such as pedestrians.
Box Girder Bridge is strong. One of its advantages is high resistance to torsion, which is twisting the object due to torque, which is a useful function if the bridge is curved. In addition, the bond canLiving larger beams and stronger flanges, allowing a longer range between the support columns that hold the bridge. However, there are some disadvantages to this type of structure. The construction can be costly for the construction and, for example, difficult to maintain.
West Gate Bridge in Melbourne Australia is Bridge Girder. Its part collapsed in 1970; Significantly improved proposals came from this tragic accident that resulted in the death of 35 construction workers. Some bridges for the nose are even designed to withstand a strong earthquake.
