West Point Bridge Design Contest 2012 Introduction • A bit about me • What is Civil Engineering? • What do I do? • The competition… A bit about me.... Do you know what a civil engineer is? What do you need to do that? • To be good at Maths and Science • To have Maths and Science Qualifications • Either go to university or…. • Do a modern apprenticeship • To enjoy problem solving • To want an exciting career! So, what do I actually do?? A quick look at bridge engineering… From the wooden suspension bridge… …to the vision of architecture and engineering combined Different types of bridge: The Clyde Arc in Glasgow Bowstring Arch Image courtesy of Glasgow City Council Different types of bridge: The Forth Road Bridge & Forth Bridge (Rail) in Edinburgh Suspension Bridge and Truss Bridge Different types of bridge: The Tay Bridge in Dundee Girder/truss Different types of bridge: Kenmore Bridge at Loch Tay Masonry Arch Different types of bridge: Skye Bridge Cantilever The future of Scottish Bridges The Forth Replacement Crossing Cable-stayed bridge Jacobs are working with Transport Scotland on this project Images courtesy of Transport Scotland The future of Scottish Bridges Cost estimate: £1.7-2.3 billion Programme: to open in 2016 Size: 2.7km long Will carry a dual carriageway across the Forth Images courtesy of Transport Scotland Some engineering principles Tension = being stretched Compression = being squashed In a triangle: in compression in compression The corners are trying to slide apart, so the bottom of the triangle is in tension In a truss•Tension is blue •Compression is red Materials: •Some are better in tension than in compression (think about an elastic band) •Some are the other way around (like stone and concrete) •You will have to experiment. The Contest Design a bridge! Plan Refine Design Review Challenge Design a truss bridge to carry a two-lane highway across this river valley Objectives • Ensure that your bridge can carry its own weight, plus the weight of a standard truck loading • Keep the cost of the project as low as possible •See Instruction Sheets! •Download software from the internet •Register your team of two online - fill in the local contest code •Use the wizard to get you started Some Rules •Work in teams of two- you must not register multiple teams •Submit your entry to the website by the deadline date and time •Cheapest design that can carry the lorry will be the winner! •The global contest rules on the Westpoint Bridge website apply The Prizes •Amazon Vouchers top 10 teams •1st- £150 of Amazon vouchers for each team member •2nd- £100 of Amazon vouchers for each team member •3rd- £80 of Amazon vouchers for each team member •And £30 Amazon vouchers for each member of the next 7 teams!!
