    • Structural Engineer Who...? MADE City Builder Academy
    • 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.
    • Definition of Structural Engineering 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
    • 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
    • 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
    • So what do Structural Engineers do? Most importantly, our structures need to be built So we must also assess our structures for buildability
    • 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?
    • Then develop one solution into details
    • 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...!
    • We also have a significant responsibility to society...
    • 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.
    • Charles De Gaulle Airport, Paris (2004) - 4 died, 3 injured Hyatt Regency Walkway, Kansas City (1981) - 114 died, 200 injured
    • 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
    • What’s  on  my  desk  now? • King  Edward’s  School,  Birmingham  – courtyard classroom extension
    • 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
