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):
In many low to moderate seismicity regions, tall and irregular buildings are common. Usually, because of their height and irregularities as defined by most current design standards, these buildings have to be designed using complex performance-based methods with non-linear dynamic analysis, or they have to be designed to be essentially elastic. This either results in a complex design procedure, or in significant overstressing of some vulnerable members. As a result this drives the design of the overall lateral stability system to become unnecessarily difficult. Based on the incremental substitution procedure (Ho & Kuang, 2014), control on the distribution of damages could be gained through reversing the evolution process (Ho & Kuang, 2012). This created the platform for a new seismic design methodology for new buildings, which is named as the direct ductility distribution method.
