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):
This paper evaluates the potential of self-centering moment-resisting frames (SC- MRFs) with viscous dampers to reduce the economic losses in steel buildings due to strong earthquakes. The evaluation is based on the comparison of different designs of a prototype steel building using as lateral-load resisting system: 1) conventional steel moment resisting frames (MRFs); 2) MRFs and viscous dampers; 3) SC-MRFs; and 4) SC-MRFs with viscous dampers. The economic losses are estimated by developing vulnerability functions according to the ATC-58 methodology. The influence of residual storey drifts on economic losses is examined by accounting for the possibility of having to demolish a building as a result of excessive residual storey drifts. Results highlight the importance of considering residual story drifts as a demand parameter to economic loss estimation; and show that the use of viscous dampers significantly improves the building’s performance for both SC-MRF and MRF, resulting in lower repair cost.
