New regulations for non-seismic design of concrete structures

Recommended Prerequisites

Engineering Mechanics and Strength of Materials

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

Knowledge of the evolution that has taken place in normative and technological terms in recent years in terms of reinforced concrete structures, focusing on the following aspects:

- understanding of the behavior of reinforced concrete elements in service conditions and at failure;

- principles, theories and models of design/verification of reinforced concrete elements.

- interpretation and application of the provisions of part 1-1 of Eurocode 2 (EC2-1-1).

- design and detailing of reinforced concrete elements, critical evaluation of solutions and development of technical drawings for their correct execution;

- analysis and design of areas of discontinuity where classical procedures (sectional models) are not applicable making use of different levels of model complexity (LoA I, II and III).
