Learning objectives
• Knowledge and understanding:
Aim of the course is to provide the fundamentals for the design of reinforced concrete, masonry and steel building under seismic actions.
• Applying knowledge and understanding:
The main skills that students should acquire at the end of the course are:
o Achievement of good ability in the structural concepts of new civil buildings subject to seismic action;
o Achievement of sufficient sensitivity to the main issues related to seismic retrofitting techniques of existing buildings;
• Making judgements:
The design and verification of structures performed with the aid of calculation codes has become current practice nowadays. The complexity of computer codes and number of structural verifications required by regulations may be a source of significant computational and conceptual errors. The student will therefore govern the procedure adopted in the current design practice, with a constant link between the theoretical knowledge and the practical applications making use of analytical calculation for the control of the results obtained with software.
Communication skills:
The confidence gained through a constant connection between theoretical knowledge - structural modelling with finite-element programs - control of the results obtained with simplified analysis of the structural response, will allow the student to possess the necessary skills for results presentation.
Learning skills:
The student will have to design a reinforced concrete building and a masonry building. The revisions of the calculation reports that will be performed during the preparation of the student final exam will allow to check the ability of student learning.
Prerequisites
It is useful the theoretical knowledge of the calculation of internal actions in frame buildings subjected to static and dynamic actions with calculation methods, either manual or numeric (it is believed that this knowledge can be gained in Module A of the same course).

Teaching methods
The course consists of lectures, course materials can be downloaded from the portal "Web LEArning in Ateneo". Some exercises will be carried out during the course to enable students to practice with structural analysis of buildings under seismic actions. Some seminars are organized by inviting engineers working in the field of earthquake engineering in order to enable students to approach the world of work, which is awaiting them.
Assessment methods and criteria
The students will have to design a reinforced concrete building and a masonry building. The examination consists in the presentation of the calculation reports and an oral discussion with the teacher. The level of students learning can be measured as follows:
Reinforced concrete building report: 50% divided as follows:
15% conceptual design;
10% skill in modelling;
10% mastery in results analysis;
10% check of numerical results with analytical calculations;
15% knowledge of theory.
Masonry building report: 50% divided as follows:
15% conceptual design;
10% skill in modelling;
10% mastery in results analysis;
10% check of numerical results with analytical calculations;
15% knowledge of theory.
