DESIGN OF STRUCTURES 1 - F/N
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.
The courses of Statics, Structural mechanics, and Structural Engineering are helpful
Course contents summary
The course treats the fundamentals of un-reinforced masonry structures design under seismic actions. The contents of the course are listed below

• Spectral response analysis: example of static and dynamic analysis for 2D frames;
• Ductility, criteria for structural regularity and behaviour factors;
• Capacity design approach;
• Combination of the seismic action with other actions, limit state verifications;
• Design and detailing of reinforced concrete frames;
• Modelling of reinforced concrete frames through finite element codes;
• Design and detailing of reinforced concrete wall systems;
• Design and verification of foundations and diaphragms;
• Existing reinforced concrete buildings: push-over analysis (theory and applications);
• Design and detailing of steel moment resisting frames;
• Design and detailing of steel frames with bracings;
• Seismic behaviour of masonry structures;
• Design and detailing of masonry buildings: theory and applications;
• Out-of-plane failure mechanisms in masonry buildings: theory and applications;
• Specific issues for existing and historical masonry buildings;
• Characterization of soil mechanics and verifications of foundations and soil;

All the teaching material is available via the portal “Web LEArning in Ateneo” (LEA UNIPR).
The course is composed of traditional frontal lectures, also with Powerpoint presentations.
Theoretical concepts are applied during the course by carrying out the step-by-step design of a masonry/wood building.
Assessment methods and criteria
The exam is written. Given a project similar to that seen during the course, the exam consists in the design of some of its structural elements. 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
As for all the laboratories, attending the courses is required.
