The course provides students with the skills for the definition of a structural concept and the design of the elements that are part of it, based on the main construction materials nowadays used, including reinforced concrete, steel, timber and masonry. The course will address the following topics: definition of the loads acting on the structures; beam theory and force method for the calculation of statically indeterminate structures, calculation of internal forces and stresses; design and verification of the structural elements and connections. The statistical characterization of the variables involved will also be shown. The ultimate goal of the course is to provide students with the knowledge needed to develop a project also from a structural point of view.
The course is divided in two modules:
(1) Design of Masonry and Timber Structures.
(2) Design of Steel and Reinforced Concrete Structures.
Course specific prerequisites
A basic knowledge of statically determinate and indeterminate structural systems and sectional analysis is required. However, a quick recall on some basic knowledge will be provided in the course.
Design of Masonry and Timber Structures
The aim of this module is to provide advanced knowledge of the design of both simple and complex timber structures, detailing and connections. A second general aim of this module is to develop the techniques required for the design, analysis, and assessment of masonry structures. Particular emphasis will be placed on limit-states design, strength design and seismic design. The use of Eurocode 5and 6 (Italian NTC-2008) will be emphasized.
Specifically, this module will also address the following main topics:
A) Timber structures.
1) Introduction to Eurocode 5 (EC5)
2) Material properties: structural timber and engineering wood products (EWP)
3) Design of structural timber elements in ULS and SLS subjected to combined stresses
4) Glulam beams with varying cross-sections: tapered, curved and pitched
5) Detailing and connections
B) Masonry structures.
1) Introduction to Eurocode 6 (EC6)
2) Masonry materials
3) Masonry design approaches and overview of load conditions
4) Compression behavior of masonry and masonry wall configurations
5) Distribution of lateral forces and flexural strength of masonry members
6) Shear strength of reinforced masonry and stability of walls
Design of Steel and Reinforced Concrete Structures
The aim of this second module of the course is to provide the skills for the design of both reinforced concrete and steel structures. Both simple structural elements and multi-storey buildings will be dealt with and the problems related to the connection of structural elements emphasized. Eurocode 2 and 3 will be adopted as reference codes for the design of reinforced concrete and steel structures, respectively.
Specifically, this module will address the following topics:
1) Instability of compressed members;
2) Concrete and steel as structural materials: mechanical material properties and their characterization;
3) Structural concept most adopted for reinforced concrete and steel structures;
4) Loads acting on the structures and their combinations;
5) Design of structural elements, for both reinforced concrete and steel structures, under axial, shear, bending and combined axial-shear-bending loading conditions.
The course is organized in lectures, once a week, and it includes theoretical lectures, exercises and design task.
