Earthquake Risk and Engineering towards a Resilient World

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

Overview

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

Review

This paper gives a general overview of SILER, a Collaborative Project funded within the 7th EC Framework Programme, aimed at studying the risks associated with seismic initiated events in Generation IV Heavy Liquid Metal reactors and developing adequate protection measures. In SILER, the attention is focused on the evaluation of the effects of earthquakes, with particular regard to unexpected (beyond design) events, and to the identification of mitigation strategies like seismic isolation.

Specific sections of the paper are addressed to the design, development and testing of the isolators (High Damping Rubber Bearings and Lead Rubber Bearings) and the most critical interface devices like flexible joints for pipelines and joint-cover of the seismic gap. These devices showed excellent behaviour during severe qualification tests in real dynamic conditions and confirmed the reliability of the seismic isolation technique.
