A double-beam drawbridge, seesaw or folding bridge is a movable bridge .It opens by rotation about a horizontal axis parallel to the water. Choose the appropriate analysis mode for the project stage—line beam, grillage, or finite element analysis—all combined with traffic load optimization. A beam bridge needs to be stiff.

Beam bridges are one of the most commonly used bridges for covering short distances, and are generally constructed on the local roads. The basic principles of bridge design are dependent on the load-bearing structure; whether flat, convex or concave. a bridge whose main structural element consists of a beam set across two or more vertical supporting members. Even when you use reinforced concrete and steel for the bridge, a span which receives heavy traffic might have a rated lifespan of just 25 years. Compression occurs on the top of the beam and tension occurs on the bottom of the beam. There are no walkways on the bridge and it features sheltered carriageways on the lower deck when very strong winds prove to be too much for vehicles to safely handle. Three main bridge areas are Foundation, Substructure, and Superstructure. The components of the bridge are picked to fit not only its use case scenario (pedestrian, highway, railway, transit or industrial bridges) but also location on which it is built, the span between its main structural beams and their basic structure (arch, beam, … Adobe Bridge is a media manager that is compatable with all other Adobe programs.
