B026315 - THEORY OF STRUCTURAL ANALYSIS AND DESIGN

Italian

The course aims to provide students with the basics for structural design and tools for the calculation of structural elements belonging to structures realized with traditional materials (concrete, steel, masonry, wood). With reference to current technical regulations, further details are given about design procedures concerning new constructions and interventions on existing structures as well.

Course notes.

The First Level Degree Course in Sciences of Architecture aims to train a professional figure possessing the conceptual and operational control of the basic methods and tools needed to operate in the field of architectural design, conducted at different scales of representation.
According to the above objectives, the course aims to provide the architect with the basic elements allowing an adequate training in the structural field, within an integrated educational path connecting the structural design with the architectural and technological components.

Knowledge of basic mathematical notions and fundamentals of Statics and Science of Constructions.

The course aims to provide students with the skills necessary for the design of a non-complex structure. It is divided into theoretical lessons alternated with practical/applicative activities. In the first part of the course, theoretical lessons prevail; they provide students with basic notions for structural organization and tools for structural dimensioning, according to procedures established by current Italian technical codes. These lessons are combined with exercises aimed at consolidating the theoretical arguments. The second part of the course is mainly devoted to the development of design applications concerning the intervention on an existing structure and the structural design of a new construction. These applications allow the development of graphical tables to be discussed during the final examination.

The final examination involves discussion of the tables drawn up during the design applications; knowledge of theoretical notions necessary for the development of structural applications is also verified.

The contents of the course are divided into the following sections:

1. MATERIALS AND STRUCTURES
Mechanical properties of construction materials: stiffness, strength, ductility.
Notion of structural model.
Structural types and their characteristics in relation to the construction material.
Structural characteristics of masonry, concrete, steel and wood constructions.
Basis of structural organization, main and secondary elements. Horizontal and vertical resistant systems, bracing systems

2. LIMIT STATE METHOD
New Italian Technical Code: new procedures for structural verification; safety and expected performance. New constructions and existing buildings.
General features of the Limit State Method. Definition of structural safety based on a probabilistic approach. Definition of Limit State: Ultimate Limit State and Serviceability Limit State.
Notion of resistant effort. Evaluation of resistant efforts of steel structural elements.
Plastic moment and plastic domain for steel sections.
Design and verification of a steel structure subjected to gravity loads.

3. EXISTING BUILDINGS
Vulnerability assessment for masonry and concrete buildings.
Mechanical behaviour of a masonry wall: stiffness, strength, ductility.
Shear strength of a masonry wall taking into account the different crisis mechanisms.
The path of knowledge for existing buildings: code requirements. Knowledge levels (LC) and confidence factors (FC).
Sizing of a steel closed frame by a simplified method.
