My presentation given at the Association for Science Education eastern Region Annula Conference at Stewards School, harlow on 13th March 2010 The main subject of the presentation is an introduction to the west Point Bridge Design Challenge and how to download and use the free software but it also covers me, the ICE, bridges and the basics of bridge design plus also the PASCO bridge kit.

30. West Point Bridge Design Challenge

31. West Point Bridge Design Challenge

33. West Point Bridge Design Challenge You can chose to create a new bridge design or load a sample

34. West Point Bridge Design Challenge You can select from a number of sample designs

35. West Point Bridge Design Challenge Which gives you an instant bridge which you can work on

36. West Point Bridge Design Challenge Or you can create a new bridge design from scratch

37. West Point Bridge Design Challenge Start by chosing deck elevation and support types

38. West Point Bridge Design Challenge Note that digging is (relatively) cheap

39. West Point Bridge Design Challenge Then select your deck material and loading

40. West Point Bridge Design Challenge And chose your template (if you want one)

41. West Point Bridge Design Challenge Tell it who you are and give your design a number

42. West Point Bridge Design Challenge Which just leaves you to design your bridge

43. West Point Bridge Design Challenge template joint member member properties draw member draw joint select element erase element There are very few basic design tools and items to use

44. West Point Bridge Design Challenge And you can soon end up with a basic bridge design

45. West Point Bridge Design Challenge test bridge Let your creative side get carried away however make sure your model is not unstable – can you see why?

46. West Point Bridge Design Challenge test bridge When you are happy you can test your bridge

47. West Point Bridge Design Challenge test bridge Looking good my friends……

48. West Point Bridge Design Challenge Back to the drawing board 

49. West Point Bridge Design Challenge Look to see where the problem lies in the load test results table

50. West Point Bridge Design Challenge And fix it by changing the member properties Select members Change material / type / size

51. West Point Bridge Design Challenge Success (but at what cost?)

52. West Point Bridge Design Challenge $356,327.71 Note cheapest in the 2010 qualifying round was $136,874.77 Review the cost calculation report for the cost breakdown

53. West Point Bridge Design Challenge Review the member properties and load test results (for diehards)

54. West Point Bridge Design Challenge $295,048.74 Iteration 12 save print Keep fiddling until you get a cheap bridge (that stands up)

55. West Point Bridge Design Challenge much bigger sag not so nice for bridge users A cheap bridge may be a bit scary to drive over though ULS / SLS

56. West Point Bridge Design Challenge My son Tom will be a scientist or engineer – note centre pier

57. West Point Bridge Design Challenge Tom doesn’t really take the cost of the bridge into account (he’s only 8)

58. West Point Bridge Design Challenge My daughter Lizzie is more the creative type (its cheap though)

59. West Point Bridge Design Challenge She may turn out to be an Architect

60. West Point Bridge Design Challenge But she does lose interest rather easily and go a little too far

61. West Point Bridge Design Challenge It doesn’t fall down (but does cost $7.5 million
