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 study presents a methodology for selecting and scaling real earthquake ground motions to be used in the estimation of nonlinear structural response. The proposed procedure explicitly considers the uncertainty in the target intensity measure with the level of spectral variability preserved in the ground motion suite. The candidate ground motion sets are constructed based on dispersion statistics about the target spectral demand. The optimum ground-motion set is linearly scaled by using an optimization algorithm that minimizes the error between scaled median and target spectra. The scaling stage ensures that the median record spectrum provides a reasonable match to target median in a previously defined period interval. The effect of the spectral variability on seismic demand estimations is investigated using various inelastic single degree of freedom structural systems. In order to investigate the impact of different selection and scaling methodologies on nonlinear structural response, the results are compared with those obtained by the Conditional Spectrum (CS) based scaling methodology. The variability in the nonlinear structural response due to the use of different numbers of scaled recordings are also examined with the aim of finding optimum number of ground motions for reliable and stable estimation of nonlinear structural behavior.
