The intent of the test burn was to compare the different floor assembly's ability to withstand the ravages of fire. The wooden i beam floor was built to support the same weight load as the 2 x 12" floor. The fireload for each was exactly the same amount of hay and wooden pallets. They were ignited at the same time.<br /> Granted, neither floor assembly was protected by sheetrock but this test indicates how much quicker a wooden i beam can fail in a fire. Also notice the heavy/black smoke that is immediately produced as the wood I beam gets heated up. This smoke is the glue in the OSB off gassing. This smoke is very toxic contains formaldehyde) and is very flammable.<br /> Wood I beams are very strong, until a fire starts....... Then they can fail very quickly and without any warning. tag:community.fireengineering.com,2009-11-26:1219672:Video:163561 2009-11-26T18:25:25.734Z Dave Walsh https://community.fireengineering.com/profile/DaveWalsh
