Structural Engineering- David Sharpe, MADE City Builder Academy 2013

  1. 1. Estates Office Structural Engineer Who...? MADE City Builder Academy
  2. 2. Estates Office Who am I? David Sharpe Profile: http://uk.linkedin.com/in/dmsharpe • I have over sixteen years experience of building structures, undertaking the structural design of new-build & refurbishment projects. • I have also been exploring recently how I can integrate structural design with the principles of low energy use, such as the PassivHaus standard, for new and retrofit projects. • Building on experience of refurbishing 20th century structures, I am also developing skills in conservation and heritage engineering projects.
  3. 3. Estates Office Structural Engineering is the art and science of designing and creating a skeleton or frame that can resist the loads that are applied to it. The skeleton or structure should be efficient and although draped in a skin or façade, the structure should be considered as architecture in its purest form. John Roycroft, BDP Definition of Structural Engineering
  4. 4. Estates Office So what do Structural Engineers do? We hold structures up! Or, more helpfully, we must ensure that a structure is: • Safe from falling down - strength • Safe from falling over - stability
  5. 5. Estates Office So what do Structural Engineers do? But also, we need to make sure that our structures can be used So we must also assess our structures for: • Deflections and vibrations – serviceability • Not prone to getting ‘old’ quickly - durability
  6. 6. Estates Office So what do Structural Engineers do? Most importantly, our structures need to be built So we must also assess our structures for buildability
  7. 7. Estates Office How do we design? Start by thinking about lots of options: • via a number of sketches / options in parallel with simple calculations • There is rarely one solution, and often must assess options against some criteria For example • What forces will be applied? • What the structure is for? • How long will it need to last?
  8. 8. Estates Office
  9. 9. Estates Office Then develop one solution into details
  10. 10. Estates Office Being a Structural Engineer is more than just design... • Structural Engineers do not work in isolation • We are part of a larger project team and need to coordinate with: • Clients • Architects • Building Services Engineers • Civil & Geotechnical • Contractors • Skills of engineering are more than maths – need to understand people and how to work with others • Also a business – need to win work, do it to budget and get paid...!
  11. 11. Estates Office We also have a significant responsibility to society...
  12. 12. Estates Office Beautiful Railway Bridge of the Silvery Tay! Alas! I am very sorry to say that ninety lives have been taken away, on the last Sabbath day of 1879, which will be remembered for a very long time.
  13. 13. Estates Office Charles De Gaulle Airport, Paris (2004) - 4 died, 3 injured Hyatt Regency Walkway, Kansas City (1981) - 114 died, 200 injured
  14. 14. Estates Office How did I get to be a Structural Engineer? • I started thinking about being involved in some form engineering around the time I was selecting options for GCSEs. • In the run up to selecting which A-levels to take, I decided to focus on the built environment, and went to chat to an architect and a civil/structural engineer. In the end, I went for Civil Engineering, and selected my A-levels – Physics, Maths & Geology – to suit the degree course requirements. • Then university – BEng (Hons) Civil Engineering – University of Liverpool • I decided to specialise in building structures, so decided to take a Masters degree – MSc Structural Design, University College London • From there started working for design companies – known as consulting engineers – starting with Arup in Cardiff in 1995. • Spent some time out on construction sites, to understand how things are built • Then went through route to become a Chartered Structural Engineer
  15. 15. Estates Office What’s on my desk now? • King Edward’s School, Birmingham – courtyard classroom extension
  16. 16. Estates Office What’s on my desk now? • Camera Platform on roof of RES Wyatt Stand, Edgbaston Cricket Ground • Dafforne Road, London – refurbishment & renovation, including energy retrofit
