Cantilever Bridge Advantages and Disadvantages: Merits: Falsework is not required other than the required for pier. • For a symmetrical bridge (that is, the sections on both sides of the tower are the same), the balance of horizontal forces and large ground anchors are not. Cantilever bridge is an excellent bridge structure, since this structure only required the one side of each cantilever to support without the bridge Pier, it allows the vehicle or pedestrian over through from under the bridge, and does not affect the traffic on first floor. The goal of the trusses in this bridge design is to distribute weight evenly along each part of the framework so that every component can share in the work. to construct a truss that would hold a relatively high efficiency score. A bridge is a structure designed to create a path over an obstruction, like a river or road. The structure of interconnecting triangles means that the load-bearing capacity of truss bridges is huge. Hyundai works the world's biggest incorporated car fabricating office in Ulsan South Korea which has a yearly generation limit of 1.6 million units. Composite materials, on the other hand, have the capability of being strong and being light weight at the same time, which is why it is used for building transportation vehicles such as airplanes that need a strong material with the lowest weight possible.

Followings are the major pitfall or disadvantages of arch bridges: Restricted span: An arch bridge will solely be of a definite size, either multiple arches are required for the muse of the structure or alternative reinforcement materials ought to be enclosed to support the loads.

Suspension, beam, arch and cantilever designs are all able to cope with our modern-day heavy loads of traffic—so why choose a truss bridge? - The bars are lightweight frame, thereby reducing static downloaded abutments, leading to the foundation does not require high beam bridge. These piers help in sharing the load from the main columns, and also enable the bridge to be extended farther from each pier, in segments. A truss bridge is the only type of bridge that allows a roadbed to be placed on the structure itself. Disadvantages of Pitched Roof. They are quite difficult to maintain.
