Bridge Builder Contest 2014

Published: 15 December 2014

A recurring feature for students from the Civil Engineering, Architecture and Fire Protection programmes is the Bridge Builder Contest organized at the Department of Civil, Environmental and Natural Resources Engineering. This year also the aesthetics was a competitive element along with the pressure test.

Autocratic judge and jury for the aesthetic part of the race was Erik Hidman. PhD in Architecture. There were actually two types of bridges that were tested during the competition, truss and girder bridge. Both can be aesthetically pleasing, girder bridge in its simplicity and truss bridge by highlighting the structure (truss) as aesthetically-bearing elements.

–  By the aesthetically accentuate the truss created a beautiful and functional bridge. The apparent carpenter joy and finish in detail enhances the design and expression make this - picture four in slideshow above - a winner, said Erik Hidman.

The winning team´s bridge only weighed a little more than 21 kg and survived the weight of 100 kg for more than 10 seconds. The team included: Axel Larsson, Tommy Aderot, Simon Burström, Jacob Fredriksson, Martin Hjort, Martin Skär, Gabriella Holmgren, Hampus Hansson and Jonas Axelsson. All of the winning team received sooner, except the prestige that entails, a prize of $ 100.

- We earned this victory, said Gabriella Holmgren.

The team that took second place had built a bridge that was about 2 kilo heavier than the winning entry.

Some mathematics was also included in this project, since all participating teams also reports its computational models of their designs. It is not always these calculations and the reality works exactly as intended.

Rules in Brief

It is up to the students to design and build a wooden bridge with specific dimensions, length and material can carry the load 100 kg for at least 10 seconds. The lightest bridge that meets these requirement wins. The bridge is built mainly of sawn timber of northern pine or spruce and nails. All groups have the same set of materials and tools.

The competition is part of a lab exercise where also technical drawings and calculations contained in the written statement. The bridge must also be dismantled for reuse after the competition.
