051708 - STRUCTURAL DESIGN
The development of a suitable solution to structural design requires, first of all, the selection of a construction material and, subsequently, the adoption of a structural typology, also with reference to the specific actions characterizing the design problem. Finally, each single structural element can be considered, defining suitable dimensions and verifying that the stress state induced by external actions is compatible with the material resistance properties. The above design process is discussed within the course. With reference to common building codes, the definition of design actions is discussed and the behaviour of columns and beams subject to axial load, bending and shear actions is investigated. Concrete and steel are considered the main construction materials and the corresponding typical structural typologies are presented.
Risultati di apprendimento attesi
Students: - gain knowledge and understanding of theories, techniques and tools useful in structural conception and its dimensioning, in compliance with the current regulatory framework; - are capable of analysing buildings, based on material properties, structural typologies and load analysis, in compliance with current regulations; - are capable of dimensioning structural elements in the relationship between form and structure.
The aim of the course is to provide the basic structural knowledge for designing structures made of reinforced concrete or steel. The course is divided in three parts: (a) complements of structural analysis; (b) behaviour and design of steel structural members; (c) behaviour and design of reinforced concrete structural members.
A- Structural Analysis
Basic statically determinate members: simply supported beam, cantilever, trussworks. Basic redundant structures: continuous beams solved using the force method.
Basis of design: Serviceability Limit States (SLS) and Ultimate Limit States (ULS)
B - Steel structures
Steel as a building material: fundamentals concerning the constitutive behaviour, laboratory tests. Design of steel structural members: elastic and plastic design. Typical structural elements, design and serviceability checks under service loads. Behaviour at the ultimate limit state. Buckling of structural elements: theoretical formulation, critical loads for different boundary conditions, role of imperfections and use of stability curves.
C - Reinforced concrete structures
Concrete as a building material: fundamentals concerning the constitutive behaviour, laboratory testing. Fundamental assumptions of R/C: reinforcement, bond and calculation hypothesis. Design of R/C columns for centric axial loads at the Serviceability Limit State (SLS) and Ultimate Limit State (ULS). Behaviour of R/C elements in bending: analysis and design for SLS (uncracked and cracked) and ULS. Typical structural elements and reinforcement layout. Behaviour of R/C elements in shear: Ritter-Mörsch truss model.
Modalità di valutazione
The exam consists of a written test; in case the written test is not completely sufficient, an oral examination is required.
