The students will learn the basics of seismic design for any type of buildings, with a focus on reinforced concrete ones. The fundamental notions of force-based and displacement-based design approaches will be grasped.
Four homework assignments are foreseen, which will address the characterization of the seismic input and the seismic design and detailing of a reinforced concrete structural wall building, in addition to a small project, to be carried out in groups.

Contenuti
The course will start with a brief review on the main aspects of the dynamic behaviour of linear and nonlinear single-degree-of-freedom systems, which represents the basis to understand seismic design. Afterwards, the conceptual seismic design of structures will be addressed. The core of the course will be the discussion of (largely enforced) force-based and (developing) displacement-based seismic design philosophies, focusing on the tools and steps required for their employment and verification. Capacity design principles, necessary to ensure a target hierarchy of ductile inelastic deformations will be explained with emphasis on the design and detailing of reinforced concrete structures with the adoption of Eurocode 8, amongst other codes and guidelines. Further attention will also be paid to the characterisation of the force-deformation behaviour of reinforced concrete structural elements as well as the modelling and analysis of reinforced concrete structures with nonlinear finite element approaches.
