Prestressed concrete structures

Recommended Prerequisites

Reinforced concrete.

Teaching Methods

The traditional blackboard lecture style is used for (1) the motivation and detailed exposition of the fundamental ideas, concepts and methods and (2) the application and illustration of the theory, by discussing the EC2 provisions and by working through selected examples in detail. The student is then expected to solve, under the supervision of the instructor, a collection of systematically arranged problems; the aim is (1) to suggest to him useful lines of disciplined thought in dealing with more complex problems and (2) to promote his autonomy.

Learning Outcomes

Learn to design prestressed concrete structures. 

Improve the knowledge about the behavior of prestressed concrete structures aiming to solve complex problems and design large concrete structures.
