2013 Bridge Building Competition

This video shows some of the wicked constructions for the 2013 Bridge Building Competition at the University of Canterbury, Christchurch, New Zealand.
The rules are: carry two people and break with three. The lightest bridge wins.

This is very interesting. After reading the description, the bridges are supposed to carry 2 people and break at 3 people(with the lightest design winning). Which I think is even more difficult than just making it as strong as possible.

[@r0xdab0x96xo]

Much more difficult. Finding a medium without trial and error is an interesting and clever concept

[@lmandrums3118]

Definitely because making a bridge strong is hard but not as hard as making a bridge strong but not strong enough to hold a certain amount of weight(3 people) so it’s very challenging and that is what makes this challenge fun!

[@ArkadiuszPL]

@@r0xdab0x96xo I am structural engineer with bridge engineering sepcialisation and I dont know if you are engineer but today we have such advance computer programs for calculations that it is not that hard at all. I always loved bridge building competitions because it is fun and teach you how to think and also you learn manual skills. BUT when you compare these '' models'' to real bridges there is very few things that connects them. I designed steel model that weight 50kg and with 5m span can take 1000kg and it will have 1,2mm deflection (max load would be at least 2000kg) So you See what proportions are in terms of weight to load. In real structure this ratio is much smaller and for Road cable stayed bridges for example it is around 0,25 (load/bridge weight). I myself designed 300m cable stayed Road bridge at my master degree diploma 😀

Even though the last bridge broke with an impressive amount of payload before failure, and although, at first, i thought that the bridge that can withstand the most payload within certain bridge building construction parameters govern by the contest was considered the winner, I realized after reading the description that it's carry two personnel, fail with three and the lightest bridge wins. This contest is awesome in the learning process. Would've been neat to see a suspension bridge but these were all beautifully crafted bridges from some great candidates.

It is to determine who have a better understanding about bridge structures

[@jayj1268]

The educational system lacks failure. It punishes you for failing, but it is there where the most learning occurs. So to have a project designed to fail, and understand how and why it’ll fail is the unlearned half of the learning function. Understand how something will succeed isn’t all there is to it, because life itself isn’t fully designed to succeed.

[@flighted2513]
