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):

High damping natural rubber (HDNR) bearings are extensively employed in seismic isolation of both bridges and buildings. In HDNR material, a filler is added to the natural rubber to increase its stiffness and dissipation capacity. However, the addition of the filler induces also a stress-softening behaviour under cyclic loadings related to the internal microstructure breakdown or sometime referred to as damage. This phenomenon may significantly influence the seismic response of isolated systems given its recovery characteristics. The present work aims to study the consequences of such softening behaviour on the seismic performance of bridges isolated with HDNR bearings. For this purpose, the response of an isolated bridge pier under different seismic inputs is analyzed by pointing out the differences between the results obtained by considering two different conditions for the bearings, one assuming the "virgin" rubber properties and the other assuming the "stable" or "scragged" properties.
