The course aims at providing both knowledge and sensitivity about the design procedures for the most common structural elements. A preliminary requirement for this is given by the knowledge of equilibrium conditions for the analysis of load propagation through structural systems; it is also assumed that the basic concepts from structural mechanics are known, in terms of stress and deformation states in the construction materials and simple structural elements. In this course, the principal construction typologies are presented with reference to common structural materials; after introducing the rules for the definition of the design actions, the methodologies in use for the safety verification of common structural elements are discussed. The expected learning objective has to do with the capability of defining the required size for structural elements under the effect of design load conditions; steel and reinforced concrete are the basic reference materials. It is also expected that students acquire simple design criteria for the choice of suitable dimensions for the structural elements, with a degree of sensitivity towards typical dimensional values. The computational tools developed in the course are subsequently applied in design studios to the analysis of complex architectural systems.

Argomenti trattati

The course focuses on the design of structural elements and buildings with special reference to steel and reinforced concrete structures.

The objectives of the course are the students' knowledge and understanding of the main concepts of structural design, capability to present and explain the main procedures to design and check the main structural elements of buildings as well as to propose and discuss the main choices for a proper conceptual design of buildings.

Specific examples of structural design of elements and buildings will be carried out and discussed during the course.
