DESIGN OF STRUCTURES 1
Learning outcomes of the course unit
• Knowledge and understanding:
Aim of the course is to provide the fundamentals for the design of masonry 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;
• Making judgements:
The student will govern the procedure adopted in the current design practice, with a constant link between the theoretical knowledge and the practical applications.
The confidence gained through a constant connection between theoretical knowledge and applications, will allow the student to possess the necessary skills for results presentation.
The student will have to design a masonry building.
It is useful the knowledge of the fundamental of structural engineering.

All the teaching material is available via the portal “Web LEArning in Ateneo” (LEA UNIPR).
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 masonry buildings under seismic actions.
Assessment methods and criteria
The written examination consists in the calculation reports and an oral discussion with the teacher. The level of students learning can be measured as follows:
Masonry building report: 100% divided as follows:
40% conceptual design;
10% load combination of actions for seismic verifications;
10% masse centroid and stiffness centroid evaluation;
10% linear static analysis;
10% internal stresses evaluation for masonry walls.
10% in-plane verification of masonry walls
10% out of-plane verification of masonry walls
It is strongly recommended to attend lessons.
