Bridge Engineering MCQ with answer and solution

Concept

Bridge Abutments

Formula

No

Step-by-step solution

This is a conceptual question with no mathematical calculation required:1. Identify the structural components: The extreme end supports of a bridge superstructure that retain the approach embankment are defined as abutments, whereas intermediate supports are known as piers. 2. Select Option B (Abutments).

Explanation

Abutments are the supports located at the extreme ends of a bridge. They support the weight of the bridge superstructure and retain the soil of the approach embankments. Intermediate supports between the ends are called piers.

Shortcut

Remember that "Abutments" are "At the Ends" (A = At the ends), while "Piers" are in the "Pair-middle" (intermediate supports).

Common mistake

Many students confuse piers with abutments and incorrectly select Piers (Option A) because both serve as vertical bridge supports; however, piers are intermediate supports while abutments are strictly the end supports that also retain the embankment soil.
