21002006 - STRUCTURAL ENGINEERING

Acquisition of basic knowledge about the mechanical behavior of the main building materials (masonry, steel, concrete) and of the main elements and structural systems made with them. Basic tools for evaluation of the structural safety, aimed to simplified constructions design. Main topics include: classification and modeling of the actions; structural materials (masonry, steel, concrete); design criteria for structural elements.

BASIC CONCEPTS FOR STRUCTURAL DESIGN
• methods and structural requirements
• structural safety: the problem of structural safety, randomness and uncertainty in structural problems, approaches for safety assessment;
• limit states design: objective of structural design, tools, service life, ultimate and serviceability limit states, design situations, basic variables (geometric data, material properties, actions and loads), classification of actions, design values of actions, combination of actions
• loads on structures: permanent loads, variable loads, snow load, wind action, distribution of actions, transfer of actions
STEEL STRUCTURES
• material: material properties, classification of structural steel, qualification tests, durability and protection, fire resistance, strength criteria, mechanical models.
• strength, deformability and stability: production processes and steel products, local and global instability, classification of cross sections, design resistance
• members in tension and compression: typical schemes, design and verification at the ultimate limit state (ULS)
• members with bending, shear and axial force: typical schemes, design and verification at the serviceability limit state (SLS) and the ultimate limit state (ULS)
• SLS for buildings: vertical and horizontal deflections, dynamic effects
REINFORCED CONCRETE STRUCTURES
• material (concrete and steel reinforcement): classification and properties of concrete, shrinkage and viscosity, classification and properties of reinforcing steel, confinement effects, steel-concrete bond, qualification tests, constitutive bond models
• bending behavior: phase 1: uncracked, phase 2: elastic cracking, phase 3: plastic cracking, analysis of section response.
• ULS for bending with or without axial force: section analysis in phase 1, 2, 3; failure regions, solving equations, design and assessment of RC members;
• ULS for shear: behavior analysis of beams without transverse reinforcement in phases 1, 2, 3 and resisting mechanisms; behavior of beams with transverse reinforcement and Mörsch truss analogy, design and verification of elements subjected to shear
• SLS (crack and stress control): SLS for reinforced concrete, evolution of cracking, crack control, tensile state verification.

Modalità Erogazione

The course is organised in theoretical lessons and design exercises, during which some basic recurring problems in professional practice are faced and solved.

Modalità Frequenza

It is compulsory to attend at least 75% of the lessons.

Modalità Valutazione

• Written Exam (required for admission to the oral exam): assessment of the ability to approach a project and assessment of simple elements in steel and concrete; duration of the exam is 2-3 hours; previous year's exam tasks are available on the professor's FTP website, which students can access freely. • Oral Exam (individual): assessment of the understanding of the topics covered in the course and the ability to tackle project problems and assess simple elements in steel and concrete; the duration of the exam is 30-45 minutes.
