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):
During extensive field surveys in the state of Uttarakhand (India) the most prevalent configurations of buildings on slopes have been identified, which can be broadly identified as step-back, and step- and set-back configurations. In addition, for buildings on steep rock slopes, foundations resting at two different levels can often be observed. The present study focuses on the seismic fragility analysis of step-back hill buildings, which is the most commonly found configuration in the Indian Himalayas. The Incremental Dynamic Analysis procedure is used for obtaining dynamic capacity curves, which are used for fragility analysis. A set of 30 ground motion time histories has been selected and scaled using the intensity measure Sa (T1, 5%). It is observed that the hill buildings designed as per the existing code provisions for buildings on flat topography exhibit a very high probability of incipient collapse for the DBE and MCE levels of seismic demand. The performance can be significantly improved by making minor changes in the structural configuration.
