Essay on The Physics of Bridges

- ... The further the supports become due to the stretching of the bridge, the weaker the beam bridge becomes, so they only span to approximately 76.2 meters on average. Therefore, this type of bridge must be able to resist twisting and bending when a heavy load is on it. Reinforced concrete and steel beams are most commonly used to make these bridges. The reinforced concrete which is strong in compression is combined with the steel beams, which strengthen the concrete in tension. These bridges can hold anything from people to cars; despite their simplicity, they can still be useful and inexpensive to build....   [tags: beam, truss, arch, suspension]

The Physics of Bridges Essay

- The Physics of Bridges The design of the bridge superstructure is based on a set of loading conditions which the component or element must withstand. A bridge engineer must take into account a wide variety of loads which may vary based on the duration of the load (permanent or temporary), the direction of the load (vertical, longitudinal, etc.), and the effect of the load (shear, bending, torsion, etc.). In order to form a consistent basis for design, organizations like AASHTO, American Association of State Highway and Transportation Officials, have developed a set of standard loading conditions which are applied to the engineer's design model of the structure....   [tags: Papers]
