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):
A 3D non-linear finite element approach is developed to study the free-field seismic ground response and the soil-structure interaction (SSI) phenomena at the Lotung site (Taiwan) during the earthquake event occurred on May 20, 1986. The site was extensively instrumented with down-hole and surface accelerometers, these latter located also on a 1/4–scale nuclear power plant containment structure. An advanced constitutive model is adopted for simulating the soil behaviour, while a linear visco-elastic behaviour is assumed for the structural model. Both the free-field and SSI analyses are carried out applying the EW horizontal component of the acceleration time history as recorded at the depth of 47 m b.g.l. The predicted ground response results are in fair agreement with the recorded motion at depth and at the surface. Also, the dynamic response of structure is well captured for this specific seismic event, thus confirming the validity of the numerical approach.
