Description

This unit will provide a grounding in the basic principles and practices of Earthquake Engineering in structural and geotechnical engineering. The emphasis will be on understanding how seismic loads affect typical building and geotechnical artefacts, how the various materials respond up to the ultimate limit state (i.e. collapse), and how the artefacts should be configured and detailed to accommodate these issues and achieve satisfactory performance. The content will be set within the context of the new European Code of Practice for Earthquake Engineering, Eurocode 8 and the associated Eurocodes for Steel, Concrete and Geotechnics. Reference will also be made to the newly evolving Performance Based Engineering paradigm, which will be the basis for the next generation of design codes.

Aims:

  1. To develop students' awareness of the nature of earthquakes and their effects on typical civil engineering systems;
  2. To develop students' knowledge and understanding of the underpinning principles of earthquake design and construction;
  3. To enable students to apply the underpinning principles to the basic earthquake design and detailing of some typical civil engineering systems;
  4. To develop students' awareness of important evolutions in earthquake engineering practice expected over the next 10 years.

Intended learning outcomes

By the end of the course, successful students will:

ULO 1. Be able to describe the origin of earthquake ground motions and how they are influenced by the source characteristics and the ground transmission characteristics, topography etc. (PLO A2, A4)

ULO 2. Be able to explain the main methods for characterising seismic hazard (magnitude, intensity, response spectra, time histories, power spectra, etc.) (PLO A2, A4)

ULO 3. Be able to explain how ground shaking leads to the dynamic response of single and multi-degree of freedom systems and how the characteristics of those systems (i.e. mass, stiffness, damping, yielding ,etc.) can be adjusted during design in order to optimise their performance (PLO A1, A2, A4, B1, B3, B5)

ULO 4. Be able to apply simplified code of practice approaches to characterising seismic actions on systems (e.g. design spectra, R-factors, time history analysis) and relate these to fundamental methods of dynamic analysis (PLO A2, A4, B5, A5)

ULO 5. Understand the philosophy of current codes of practice (e.g. Eurocode 8, force based design, capacity design) as well as the emerging paradigm of Performance Based Engineering (PLO A5)

ULO 6. Have explored the application of code of practice approaches to the conceptual and detailed design of some typical steel, concrete, and geotechnical systems (e.g. buildings, bridges, foundations, retaining walls) (PLO A5, A8)

ULO 7. Have experience of the application of typical computer packages in seismic design (e.g. Oasys GSA, Matlab, OpenSEES) (PLO A1, A2)

ULO 8. Be aware of advanced issues and technological solutions such as base isolation, tuned mass dampers, active dampers, seismic qualification, secondary system response, etc. (PLO A2, A4)
