Bridges

Recommended Prerequisites

Analysis of Structures, Reinforced Concrete, Steel structures and Foundations.

Teaching Methods

Presentation of theoretical concepts, regulatory models and illustrative examples using oral and audio-visual media.

Autonomous work of students in computer lab with teacher's guidance and discussion of the design project.

Visit to a construction site of a bridge.

The final classification results from the weighted average of two classifications: (i) classification in the design project (60%), and (ii) classification in the oral exam (40%).

Learning Outcomes

The main purpose of the course is to provide students with the required knowledge to carry out a design of a motorway bridge.

Work Placement(s)
