In this project it is presented the design and simulation of a tubular metallic bridge for vehicles up to 50 ton, which is constituted of a single rail.
In the design they were considered two cases, one critical and the other one good, the first one happens when the truck moves to a side, resulting in that the load is not distributed symmetrically in all the elements of the bridge. And the good case and insurance is when the truck is mobilized by the center of the bridge, that which allows a correct acting of all the elements that you they conform the bridge.
The material that prevails in the design is the structural steel. 70% of the vehicular bridge is conformed of metallic pipe; and the rest conforms it profiles "I"; as well as nonskid irons.
The bridge presents an area of security, which allows the pedestrians to be mobilized with security; in a same way it possesses the respective signaling as it is: the allowed maximum weight of the vehicle, as well as weight maximum for axis.
The bridge rests on two pillars of concrete, which are separated by a creek; these pillars allow the sure and reliable stability of the bridge.
The bridge is designed in such a way that, a single wheel leans on on the profile "I"; getting that the load of the truck is distributed mainly in a correct way the bridge. In each support of the bridge it presents neopreno whose function is of absorbing the vibrations caused by the vehicles; as well as of allowing that the material expands or contract.
To improve their stability it presents feet friends whose objective is of absorbing the load in 70%, allowing that several support points exist, which begin avoiding that the maximum load concentrates on four points jointly. The bridge is designed in such a way that the efforts taken place by the loads, don't surpass 70% of the permissible effort, because they exist trucks that surpass the limit of the load, putting in risk the security of the bridge.
The vehicular bridge was subjected to loads of earthquake of great magnitude, that which allows to guarantee that in front of seismic conditions its behavior will be safe. |
