Syllabus
Obiettivi Formativi
The goal of the course is to provide an introduction to materials, construction practices, structural behaviour, analytical methods, and typical code requirements for the design of new masonry buildings and the evaluation and retrofit/rehabilitation of existing ones, with special regard to seismic action. The student will learn how to calculate the structural response of masonry elements and systems subjected to gravity loading, lateral loading and seismic loading. In addition the student will learn the principles of design of new masonry structures, the methods for seismic assessment of existing ones and the relevant strategies and techniques for retrofit.
Prerequisiti
The student should have command of the basic concepts of solid mechanics, structural analysis and design which are typically taught at BSc level in Civil Engineering curricula. Furthermore, he/she should know the concepts taught in the course of "Fundamentals of seismic design"
Metodi didattici
The course consists of a series of lectures, taught in English. The support material (Powerpoint slides, scientific papers) will be in English and will be made available to students in pdf format before the lectures. The lectures are accompanied by worked application examples. The students during the course will also be asked to solve problem/homework assignments relevant to selected topics treated in class. Practical/lab training sessions are also foreseen on nonlinear analysis of masonry buildings.
Verifica Apprendimento
The final grading will be based 40% on the homework assigment and 60% on the final exam. The final exam is a written test consisting of a first "closed books" section (1 hour) where the student is asked to answer to a series of questions on the programme, and a second "open books" section (2 hours) where the student will be asked to solve numerically a series of problems.
