Welcome to the website of the Society for Earthquake and Civil Engineering Dynamics (SECED). SECED was founded in 1969 to promote the study and practice of earthquake engineering and structural dynamics, including blast, impact, and other vibration problems. SECED is also concerned with the study of societal and economic ramifications of major earthquakes.


Bryan Skipp, 1929-2021

We are deeply saddened to announce that Dr Bryan Openshaw Skipp died on Thursday 26 August in London. He was 91.

Bryan was an eminent scientist and engineer, with an enormous contribution to seismic engineering in the UK through his work with Soil Mechanics Ltd, as a member of the Seismic Hazard Working Party and through his contribution to the Eurocode 8 suite of documents. Bryan was a former Chairman and Life Member of SECED. He had numerous publications in learned journals, sat on diverse committees and had lectureships and examinerships in institutions in Britain and overseas.

The photo shows Bryan at the tiller of his Polish-crafted timber folkboat, the Cyranka, off the Essex coast, in late spring 1977.

Steel Reinforced Grout (SRG) composites, comprising Ultra High Tensile Strength Steel (UHTSS) textiles embedded in inorganic matrices, have experimentally proved effective for a number of structural retrofitting applications. Nevertheless, existing knowledge is mainly based on the behaviour of SRG systems with a single textile layer, whereas the use of more plies may be required when strengthening large structural members. This paper presents the preliminary results of an experimental study on SRG composites comprising multiple layers of galvanised UHTSS textiles within a geopolymer mortar. Single-lap bond tests were carried out to investigate the effect of number of plies (one, two or three) and fabric density (4 or 8 cords/in) on the SRG-to-concrete bond performance, which is crucial for the effectiveness of the retrofitting work.
