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):
The current paper demonstrates the application of displacement-based procedure in the seismic safety assessment of large concrete dams. Two dam structures – double-arch and gravity, are used as case studies and analysed through conventional force-based approaches, for various Seismic Levels. Nonlinear static analyses are used for assessment of structural capacity and nonlinear dynamic analyses – to obtain the maximum response for each Seismic Level. The dams’ safety is assessed totally based on displacements through displacement-based damage indicators in the form of Damage Indexes (DI) and Safety Factors (SF). The DI accounts for the accumulated inelastic deformations in the structure and are related to predefined Damage Levels (DL), while SF evaluates the structural safety margins in terms of seismic load intensity.
