Bridges and Engineering Design

Front

What is a truss bridge?

Back

A truss bridge is a type of bridge that uses a framework of triangular shapes to support the load. It is known for its strength and efficiency in material use.

Front

What is a beam bridge?

Back

A beam bridge is the simplest type of bridge, consisting of a horizontal beam supported at each end. It is ideal for short spans and is cost-effective.

Front

What is a suspension bridge?

Back

A suspension bridge is a type of bridge where the deck is hung below suspension cables that are strung between towers. It is suitable for long spans.

Front

What is an arch bridge?

Back

An arch bridge is a bridge that uses an arch-shaped structure to support the load. The arch transfers the weight to the supports at either end.

Front

What is an abutment in bridge design?

Back

An abutment is a structure at the ends of a bridge that supports the weight of the bridge and holds back the earth.

Front

What are the main components of a bridge?

Back

The main components of a bridge include the deck, supports (abutments and piers), and the superstructure (trusses, cables, etc.).

Front

What factors influence the choice of bridge type?

Back

Factors include span length, load requirements, cost, site conditions, and aesthetic considerations.

Front

What is the purpose of a bridge deck?

Back

The bridge deck is the surface of the bridge where vehicles and pedestrians travel. It must be strong enough to support the load.

Front

What is a cantilever bridge?

Back

A cantilever bridge is a bridge that is supported on only one end, with the other end extending outwards. It is used for longer spans.

Front

What is the significance of load distribution in bridge design?

Back

Load distribution is crucial in bridge design to ensure that the weight is evenly spread across the structure, preventing failure.
