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

The seismic protection of existing buildings is still a matter of great concern. In most historic towns of the Mediterranean area, where the seismic hazard is high, buildings are hundreds of years old. In these cases, although passive structural systems installed underneath the buildings can be an option, installation procedures are expensive and not always feasible. The idea of using ground improvement techniques to modify ground properties in the vicinity of the building in order to mitigate seismic shaking is therefore appealing. In this work the problem has been investigated through two centrifuge tests, to check the possibility of using novel grouts to create continuous soft isolating barriers,. The tests have been carried out at the Schofield Centre in Cambridge (UK). In the first test a horizontal continuous soft layer has been used, while in the second one a more realistic V- shape configuration was created in the ground. The model ground layer was prepared as a 30 cm dry sand, while the soft layer was made by using latex balloons filled with a water Super Absorbing Polymer (hydrogel).
