The course intends to deepen some topics already introduced in the previous structural design design course, and to address others of main relevance for understanding the mechanical response of reinforced concrete structures. The main objectives are: • understand the mechanical behavior of reinforced concrete structures and their components at the SLS and ULS; • Acquire the ability to design the main structural elements subjected to normal, shear and torsion actions, single or combined each other; • Understand the link between the design procedures inspired by the concepts learned in previous courses and the codes and practical limits (National and European codes of practice)
Course Prerequisites
Knowledge of the basic elements of theory and design of the constructions courses is required.
Teaching Methods
Lectures focused on the description of structural typologies, materials used and characterization tests; Lectures on the analysis and design of one- and two-dimensional elements subjected to normal, shear and torsional actions Exercises related to the aspects of calculation and design of one-dimensional elements Laboratory lessons aimed at a better learning of the behavior of materials;
Assessment Methods
Homework assigned during the course on the design of reinforced concrete (RC) structures. Alternatively, completion of a full design project for an RC structure to be discussed during the oral exam. The oral exam focuses on assessing the learning of both theoretical and applied aspects. Admission to the oral exam is contingent on a positive evaluation of the homework.
