Architecture

Structural materials: concrete and steel. Structural safety and performance requirements. Actions on constructions: dead loads, live loads, earthquake, wind, snow, temperature, exceptional actions. Reinforced concrete structures: structural analysis, safety verifications, ultimate limit states (axial force, bending, shear, torsion), serviceability limit states, details. Steel structures: ultimate limit states (tension, compression, bending, shear, torsion), element stability, serviceability limit states, bolted joints, welding joints. Outline on structural design in seismic prone areas. Structural design of a residential building (structural analysis, loads, verifications of slabs, beams, piers, foundations).

In order to understand the teaching content and to achieve the learning objectives, it is essential that the student has acquired knowledge of the contents of the Structural Mechanics and Construction Science courses, and in particular the following topics: 1. Static of isostatic elastic beams and determination of the stress characteristics, such as cutting, bending moment, torsion, any normal stress; 2. Moments of inertia of geometric figures; 3. Technical theory of the beam at De Saint Venant.

Lectures and structural design.

In the initial part, the course - corresponding to the subject of Construction Technique - takes place with theoretical lessons and application exercises. With the former, the basic preparation for the analysis of the state of deformation and stress of real structures is completed; in the applications, elementary examples of stress calculation and safety verification are then addressed, with discussion of alternative solutions. Since it is not possible to delve into the discussion relating to structures made of each material (masonry, steel, reinforced concrete, wood, aluminium, etc.), the detailed discussion essentially refers to structures in "structural concrete", a term which today indicates the whole of reinforced and pre-stressed concrete; this is because these are by far the most frequent in Italy and offer the greatest insights into peculiarities in the analysis of their behavior. The program is divided along the following lines: - identification of the load-bearing structure in a construction - representation models of actions, materials and structure - safety requirements - technical regulations - properties of structural materials - security verification criteria and procedures - analysis of structural concrete elements - foundation and containment structures - most significant structural typologies and examples. Construction systems and procedures are also illustrated using projections and graphs. Project The students, in groups of maximum 3 people each, begin the development of a guided project of a structure after about a month from the start of the Laboratory. The theme is chosen by the students on an architectural basis, possibly corresponding to their own compositional project, which they already have, in order to directly address the examination of the structure. The project consists of a set of graphic documents (carpentry and reinforcement drawings with a variable number of around 10) and a detailed calculation report. Students are required to continuously develop the design work, within the time limit of the Laboratory. The teacher's assistance extends for the duration of the calendar year of attendance (October-October).

Construction Science and Structural Mechanics exams

Technical Standards for Construction (2008, updated 2018 and subsequent), and related instructions for application, course notes.

Mandatory classroom attendance is expected

The exam is both written and oral, and consists of theoretical questions on the scheduled topics and any discussion of the project. The exam can be accessed only after approval by the teacher of the project documents (report and tables) which must be delivered before the exam via email.

During the lesson time, theoretical lessons will alternate with practical exercises carried out manually and with the aid of the computer and reviews of the project progressively carried out.
