Prestressed concrete structure & bridges

Presentation

Programme (detailed contents):

Prestressed concrete structures

Design rules (EC2): minimum requirements towards cracking, stress limitation, minimum reinforcement and various layouts, calculation of the minimum prestress force, calculation of the prestress losses – Tensioning stages – Stress control – Calculation of the stresses in cracked cross-section under serviceability limit state – Calculation of the reinforcement areas.

Bridges

Terminology, bridge classification – Data for the project, design procedure – Technical regulation – Foundations: design and execution – Supports: piers and abutments – Superstructures: wearing surfaces, barrier walls, bearings, pavement join, drainage, sidewalks – Concrete bridges: materials, field of use, pre-design, execution – Steel bridges: materials, field of use, joints, classification, pre-design, execution.

Organisation:

Lecture, tutorials project.

Objectives

At the end of this module, the student will have understood and be able to explain (main concepts):

•  Technology, design and calculations of a prestressed concrete structure;
•  Technology and design of metallic, concrete or composite bridges.

The student will be able to:

•  State the required assumptions;
•  Calculate a prestressed concrete structure;

Define the technical choices for designing a bridge.

Needed prerequisite

Reinforced Concrete and prestressed concrete

Structural analysis and engineering

Form of assessment

The evaluation of outcome prior learning is made as a continuous training during the semester. According ot the teaching, the assessment will be different: as a written exam, an oral exam, a record, a written report, peers review...
