Award winning LEGO bridge

CHEOPS competition

group of 3 | 2010

 

A complete bridge consisting of only LEGO bricks. It spanned 1,5 meters and had a weight of just a few kilograms. By using a well-known bridge-building technique we came up with a simple design. The connections however are really thought into the material. LEGO connections are strong in compression, and very strong in sheer-tension. Bending moments however are fatal for LEGO connections and we tried to avoid bending moments.

 

By making tension and compression bars, connected by sheer connections resulted in bridge with a total load capacity of 72,985 kilogram! We became first in the competition, the second place bridge had only 15 kilograms to show the difference in performance. Until today nobody defeated the record.
