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

Review

The paper describes a wide testing campaign carried out on full scale prototypes of elastomeric isolators – both high damping rubber bearings (HDRB) and lead rubber bearings (LRB) – within the framework of the EC-funded SILER research project. The prototypes tested were designed for two reference nuclear power plants, the ELSY reactor and the MYRRHA reactor. Due to the typical huge masses of NPP, the related isolators often have large sizes. HDRB prototype is circular, with a diameter of 1350 mm; LRB prototype is square, with a side of 1250 mm, and four lead cores. The prototypes were subjected to different tests. One prototype was subjected to a complete type test campaign according to the European Standard EN 15129:2009, as well as to 3-D tests applying contemporarily displacement time-histories in two horizontal axes and vertical load time-history. Failure and post-failure tests were also performed, showing that the isolator, even after failure, is still able to sustain the vertical load and the horizontal displacement.
