Objectives

The course of «Elements of Structural Engineering», describing the topics that will be studied in depth during the teaching of Structural Mechanics (ICAR/08) and Constructions Technique (ICAR/09), intends to provide the students with basic notions on the main aspects of the building materials and the design of the structural system that “makes the buildings stand”. While Structural Mechanics deals with the main mechanical principles underlying the behaviour of materials and structures, Constructions Technique addresses the calculation and design of structures.
In Italy, the principal building materials are:
- reinforced concrete (concrete + steel)
- masonry
- steel
- timber
Other building materials are not currently regulated by the Technical Standards for Constructions.
With the knowledge acquired during the course, the students will be able to:
(1) Analyse an existing construction system and identify the main structural, architectural and technological components;
(2) Determine the main geometrical, physical and mechanical properties of structural elements;
(3) Distinguish among different loading conditions and perform simple load analyses;
(4) Solve elementary static problems;
(5) Graphically represent a structural system with its load-bearing elements through plans, sections and elevations;
(6) Approach the design of new constructions.

Teaching Methods

The Course is organized in modules and includes:
a) Frontal teaching classes;
b) Four individual assignments on different pre-established topics:
1. load analysis of a typical brick-concrete floor;
2. determination of masonry quality index;
3. data analysis from experimental compression and traction tests;
4. resolution of simple isostatic systems;
c) Progressive elaboration of a project work (either in group or individually) concerning:
• Analysis of an existing construction with identification of the main structural, architectural and technological components;
• Determination of the structural system with its load-bearing elements;
• Graphical representation of carpentry drawings, sections and a construction detail.

Evaluation methods

Verification of learning:

The learning verification methods will consist of:
- Instant polls and oral presentations of the assignments;
- Regular reviews of the project work;
- Final oral examination with presentation and discussion of the project work, followed by three to five questions concerning the entire program of the course.

Assignments and project work are mandatory to be admitted to the final oral examination. The committee will evaluate the correctness, completeness and organization of the deliverables and will assess the property of language, degree of detail and clarity of exposition of the student while answering to the oral questions. The final grade (out of thirty) will be computed as follows:
20% for the assignments;
40% for the project work;
40% for the final oral examination.

Contacts/More Information

Guided visits to the laboratory are foreseen for carrying out experimental tests for material characterization.
