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 the Standard for Seismic Evaluation of Existing RC Building of Japan (2001), the lower limit value of concrete compressive strength for the existing RC building is defined as 13.5 MPa, and the RC buildings are considered unsuitable for seismic retrofit if the compressive strength of concrete is lower than the limit. In this study, a novel seismic retrofit technique using external pre-tensioned high-strength hoops and steel plates is applied to the low strength RC column with smooth rebar and poor shear reinforcement under axial force ratio of 0.31 and 0.57. The experimental results show that both the ductility and the lateral capacity of the specimens can be improved significantly. Moreover, nonlinear analyses of the non-retrofitted and retrofitted specimens are carried out using VecTor2. The results from numerical models agree well with the experimental results.
