Society for Earthquake and Civil Engineering Dynamics
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.
SECED 2015 featured the following keynote speakers (affiliations correct at the time of the conference):
Comparison of Different Analysis Methods on a Theoretical Case Study
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.
