Seismic Design of Steel Structures a.y. 2020/2021

Programma

The course provides information on seismic design of steel structures for buildings. First, the types of steel structures for seismic resisting systems are introduced, along with a description of relevant engineering properties of the steel material. Subsequently, specific information is provided on the seismic design and analysis of two structural types: (i) concentrically braced frames (CBFs) and (ii) moment resisting frames (MRFs). Eventually, fundamental issues for the seismic response of alternative structural systems (e.g., eccentrically braced frames, buckling-restrained braced frames) are introduced and discussed.
