What is a weakness of an arch bridge?

The weight of all of an arch's parts holds it together, making building difficult. An arch bridge has two main weaknesses: first, its weight causes it to sag over time unless reinforced with steel rods or wires; second, its truss structure makes it susceptible to vibration. An arch bridge has several advantages over other types of bridges. It requires less material than a beam-and-fence type structure and is thus considered environmentally friendly.

But tied-arch bridges are not perfect.

What makes a bridge strong?

Actually, the arch is what makes the bridge strong. The arch allows the load to spread out instead of pushing straight down. The load spreads out to the abutments, which are supports on the ground at both ends, which keeps the ends of the arch bridge from breaking apart.

Is a beam bridge expensive?

Beam bridges may be costly even for rather short spans, since expensive steel is required as a construction material.

How do arch bridges work?

1. Arch bridges provide a finite span with each set of abutments.#N#You can cover an indefinite span with an arch bridge if you wish, but there is a catch to that process. You’ll need to use multiple arches within the design to make that happen. That’s why you’ll see the stacking design used in the ancient Roman structures that are still standing today – usually 2-3 stories worth of support. If you increase the length of the bridge, then you must add more arches.
