Earthquake Risk and Engineering towards a Resilient World

9 - 10 July 2015, Homerton College, Cambridge, UK


SECED 2015 was a two-day conference on Earthquake and Civil Engineering Dynamics that took place on 9-10th July 2015 at Homerton College, Cambridge.

This was the first major conference to be held in the UK on this topic since SECED hosted the 2002 European Conference on Earthquake Engineering in London.

The conference brought together experts from a broad range of disciplines, including structural engineering, nuclear engineering, seismology, geology, geotechnical engineering, urban development, social sciences, business and insurance; all focused on risk, mitigation and recovery.

Conference themes

  • Geotechnical earthquake engineering
  • Seismic design for nuclear facilities
  • Seismic hazard and engineering seismology
  • Masonry structures
  • Risk and catastrophe modelling
  • Vibrations, blast and civil engineering dynamics
  • Dams and hydropower
  • Seismic assessment and retrofit of engineered and non-engineered structures
  • Social impacts and community recovery

Keynote speakers

SECED 2015 featured the following keynote speakers (affiliations correct at the time of the conference):

  • Peter Ford and Tim Allmark, Office for Nuclear Regulation, UK
  • Don Anderson, CH2M HILL, Seattle, USA
  • Bernard Dost, Royal Netherlands Meteorological Institute, The Netherlands
  • Anne Kiremidjian, Stanford University, USA
  • Rob May, Golder Associates, Australia

The author works for a nuclear licensee, and was responsible for drafting the design document that specifies the requirements for seismic design (MED, 2009 updated 2014). Within this document is the statement that design to achieve ductility is just as important as strength design. This paper examines the background about why this statement has been made; and how ductile detailing can be achieved in practice.

The paper starts with a discussion about what is meant by ductility in the abstract then concentrate on what is achieved by ductile design. A simple example based upon comparison between a conventional braced frame and an eccentrically braced frame is used to illustrate this. This example is used to show how ductile details can protect a system and be used to demonstrate the capability of a structure to resist earthquakes beyond design basis.

The paper continues by describing some of the practical ways in which ductility can be incorporated into real structures taking account of the principal that stronger is not always better when considering seismic design. Reference is made to ACI 2013 for concrete structures; and to ANSI/AISC 341, 2010, for steel structures.

The paper concludes with real examples where ductile detailing has been used for nuclear projects. Examples will cover notched connections and special concentric bracing for storage racking; and use of special concentric bracing for strengthening an existing structure.
