Earthquake Risk and Engineering towards a Resilient World

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


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

In the Standard for Seismic Evaluation of Existing RC Building of Japan (2001), the lower limit value of concrete compressive strength for the existing RC building is defined as 13.5 MPa, and the RC buildings are considered unsuitable for seismic retrofit if the compressive strength of concrete is lower than the limit. In this study, a novel seismic retrofit technique using external pre-tensioned high-strength hoops and steel plates is applied to the low strength RC column with smooth rebar and poor shear reinforcement under axial force ratio of 0.31 and 0.57. The experimental results show that both the ductility and the lateral capacity of the specimens can be improved significantly. Moreover, nonlinear analyses of the non-retrofitted and retrofitted specimens are carried out using VecTor2. The results from numerical models agree well with the experimental results.
