Seismic engineering

CIVIL-522 / 6 credits

Teacher(s): Lignos Dimitrios, Saloustros Savvas, Vanin Francesco

Language: English

Summary

This course deals with the main aspects of seismic design and assessment of buildings including conceptual design. It covers different structural design and evaluation philosophies for new and existing reinforced concrete, steel and unreinforced masonry buildings.

Content

  • Introduction (seismicity worldwide and in Switzerland, typical failure modes of buildings and their primary structural elements)
  • Conceptual seismic design
  • Seismic analysis methods (response spectrum method, equivalent lateral force method)
  • Design philosophies (conventional design and capacity design)
  • Design an evaluation methods (force-based and displacement-based methods and their advantages and disadvantages, N2 method, risk-based assessment according to SIA 269/8)
  • Seismic design of reinforced concrete wall buildings (capacity design of reinforced concrete walls)
  • Seismic design of steel buildings (moment-resisting frames, braced frames, eccentrically-braced frames)
  • Seismic design and assessment of unreinforced masonry buildings (overview on typologies of masonry buildings, capacity and demand of in-plane and out-of-plane modes, seismic response of historical masonry buildings)
  • Seismic retrofit of buildings with supplemental damping devices (buckling-restrained bracings, friction dampers)
  • Seismic retrofit of , unreinforced masonry buildings

Keywords

Seismic design and assessment of buildings, reinforced concrete buildings, steel buildings, unreinforced masonry buildings, seismicity, supplemental damping, seismic retrofit.
