Objectives
The aim of the course is to analyse the theoretical principles and the theoretical background for the design of reinforced concrete structures under static loads. Particularly, the course provides the student the basic criteria and methodologies for the structural design and analysis of simple reinforced concrete structural elements, i.e. beams and columns, and simple reinforced concrete structures, i.e. 2d frames and slabs. A general introduction to the safety criteria for structures is discussed with a specific reference to the limit state methods included in the more recent Italian and European code format recommendations. Matrix methods for structural analysis are also covered. The course provides also the tools and the basic methods for the design and verification of simple prestressed concrete structures. The course includes lectures and laboratory. Laboratory is of special importance because it analyses the content of the theory by the development of problem-solving and design sessions allowing the student to integrate the theoretical principles with the necessary information of design techniques derived from practice and design codes.
Prerequisities
Knowledge of the contents of Construction Science is essential

Evaluation mode
The exam consists of written and oral parts. Written part will focus on problem-solving exercises on the different topics of the course such as structural analysis of 2d frames; design and analysis of reinforced concrete elements; matrix analysis. Oral exam will focus on the discussion of the written exam, the two term projects and all the topics treated during the course.
