The 2012 ASCE/AISC Student Steel Bridge Competition rules have been posted on the AISC website. Among other changes, the formula for determining structural efficiency has been reworked for 2012, generally increasing the cost based on weight compared to the deflection-based cost.
The site conditions for this year’s challenge prohibit the use of temporary piers or barges in the river, although there will be a midstream cofferdam (furnished by others). The bridge again requires a cantilever section on one end, although the bridge dimensions have been changed from last year. Numerous other updates have been incorporated into the 2012 rules.
The preliminary round of bridge competition consists of 18 regional events held each year throughout the spring. The 2012 National Competition will take place at Clemson University on May 25-26.
