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

Review

The estimation of design earthquake characteristics on the ground surface is based on regional seismic hazard assessment, detailed site characterization, and site response analyses utilizing available data concerning geotechnical and geological site conditions. Large number of hazard compatible acceleration records are used for site response analyses to account for the variability and scatter observed in the acceleration records. An important step in site specific response analysis is the selection and scaling of the input acceleration records. The effect of scaling of input acceleration records with respect to peak ground acceleration and acceleration response spectrum were evaluated. Two slightly different probabilistic interpretation of the calculated results are presented to estimate earthquake characteristics on the ground surface. A case study for a selected site accounting for the variability in the site conditions is presented to demonstrate the applicability of the proposed methodology. Relatively large number of acceleration records compatible with the site dependent earthquake hazard in terms of probable magnitude range, distance and fault mechanism recorded on stiff site conditions were used as input acceleration records for site response analyses conducted for each soil profile.
