Blast design uses UFC 2012.
JEI Structural Engineering is committed to helping you navigate through codes and regulations. So bring us in early for best results.
1) Must design for 2 times the glazing resistance now. Previous 2007 UFC 4-010-01 requirements allowed for frame design for the static 3 sec load and the connections for 2 x the 3 sec load.
2) Most Manufactures systems have been tested to previous 2007 UFC stand-off distances. The 2012 UFC allows for stand-off distances much less which can create very large blast loads that systems have not been tested for – so check this out before selecting the systems as engineering, fabrication and installation cost may be greatly affected.
