Scotland may not be a hotbed of seismic activity but Edinburgh Napier is at the epicentre of innovative research that could save lives in earthquake-affected parts of the world. And it all started with cycle paths In April 2015, Nepal was struck by an earthquake which killed 9,000 people. It also destroyed many of the country’s historic structures, including the 16th-century Kasthamandap temple after which the capital city Kathmandu is named. Now researchers at Edinburgh Napier are working on an innovative method of retrofitting existing buildings and monuments to protect them from future earthquakes – and the genesis of the project can be traced back to work at the Mountain Bike Centre of Scotland. Dr John McDougall, Director of Research for the School of Engineering & the Built Environment, who is leading this project, explains: “We were looking at the use of shredded rubber to improve the resilience of the mountain bike trails and the more we worked on the project, Dr John McDougall the more it became apparent that this could have some significant application in managing the dynamic properties of the ground to cope with seismic disturbances. “It’s quite a small step for us but at a public level I can see that it’s a huge leap from Glentress mountain biking to somewhere on the tectonic margins of the earth where buildings are falling down and people are dying in large numbers.” Up until now, work in this area has focused on protecting new-build structures but John and PhD student Juan Bernal- Sanchez, together with geotechnical engineering colleagues Dr Daniel Barreto, Dr Marina Miranda and Dr Katerina Marinelli, believe they are developing a novel way of installing a shredded rubber and sand mixture that will allow existing structures to be protected. The shredded rubber and sand mixture can be retrofitted to protect existing buildings 5 Story continues
