Answer 2

The actual assembly isa matter of fabricating steel frame sub-assemblies that are then lifted into place on the built and prepared abutments and piers, by crane, and bolted together.

The complicated part is designing it: a matter of understanding and calculating the various stresses and resulting strainsthe structure will have to withstand in service. This is ahighly mathematical field..

Answer 3

Truss bridges are most often found in smaller, older bridges.

A Truss bridge has its load-bearing structures composed of a series of wooden or metal triangles, known as trusses. In science class we learn that the triangle shape cannot be deformed by stress (load over a length or area). That's why trusses, the triangles, are used.

But the length of such bridges is limited by the overall weight of the bridge acting on the mid-way and causing it to sag or even collapse under its own weight. And that's why we don't see comparatively long truss bridges.

Longer and newer bridges tend to be suspension bridges, like the Golden Gate Bridge, which is under 100 years old. The suspension cables solve the mid-way sag that longer bridges inevitably encounter.

For a long spans mainly.
