DESIGN OF STRUCTURES 1
Learning outcomes of the course unit
Knowledge and understanding:
At the end of the course the student will learn the theoretical bases and the fundamental methodologies for the design and verification of r.c. floors and for the comprehension of the static behavior of some widespread typologies of r.c. and masonry structures
Applying knowledge and understanding
The student should acquire all those skills which are the basis of a conscious design and will be able in a systematic way to fit within the building process.
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 be able to design the reinforced concrete elements and masonry structures treated during the lessons.
The courses of Statics, Structural mechanics, and Structural Engineering are helpful.
Course contents summary
The first part of the course aims to provide the fundamentals for the structural design of reinforced concrete diaphragms as well as of some widespread typologies of r.c. elements. The second part of the course deals with the design of masonry buildings
The contents of the course are listed below:
1. Design criteria for horizontal diaphragms, and for link structures, in particular:
- Characterization of the most used structural materials: concrete, steel, wood.
- Construction techniques of diaphragms: floors in reinforced concrete, steel, or wood.
- Reinforced concrete floors: dimensioning, structural details, design and verifications.
- Stairs: structural schemes, dimensioning, design and verifications.
2. Analysis of design features of reinforced concrete elements, such as:
- design for bending and shear of reinforced concrete beams without shear reinforcement, according to limit state method;
- static behavior and design features concerning corbels;
- static behavior and design features concerning deep beams;
- problems concerning foundations at different levels and with different soil bearing capacity.
3 Design of masonry structures
- mechanical propertie of masonry
- Geometry of masonry buildings
- Structural details
- Design of masonry elements.

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 written examination consists in the calculation reports and an oral discussion with the teacher. The level of student learning can be measured as follows:
R.C. elements design: 80% divided as follows:
30% ULS bending and shear verification of beams without shear reinforcement
20% r.c. stair design
20% corbels design
20% deep beams design
10% issues concerning foundations
Design of masonry elements 20%
30% strength of masonry walls (compression, bending, shear)
20% geometry of masonry buildings
As for all the laboratories, attending the courses is required.
