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

This paper aims to compare the different structural analysis methods described in Eurocode 8-2 and specialised literature dedicated to bridge seismic design, such as force- based and displacement-based modal spectral analysis, push-over analysis (different alternative approaches) and non-linear dynamic time-history analysis. For this purpose, those different methods are applied on a theoretical case-study consisting in a 306 meters long prestressed concrete deck, reinforced concrete piers bridge, located in in high seismic zone of the French seismic zoning and designed for ductile behavior alternatively according to Eurocode 8-2 and the former French seismic rules “AFPS92”.

Besides the theoretical and practical comparison of the different methods of analysis and associated results, the study also highlights the main differences and changes between Eurocode 8-2 and former French seismic rules “AFPS92”. In the end, the paper addresses some upgrading propositions to Eurocode 8-2 text and content.
