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 presents the results of a series of finite element models of RC beam- column joints with and without fibre-reinforced polymer (FRP) retrofit. The modelled specimens form part of an experimental campaign and this analysis aims at informing the design of experiments. The effect of slab and transverse beams as well as of reinforcement detailing were investigated and the results used to design a simple step-by-step FRP retrofit strategy. It was found that FRP strengthening of the joint in shear was needed to concentrate damage in the column. Adding flexural strengthening and column confinement, the load capacity of the specimen was increased by 10% in the model, preventing yielding of the column bars and reducing damage in the joint. The results of the models will need to be checked and calibrated against experimental data once the tests have been conducted.
