2005 SJI Standard Specification forJoist Girders1004.6 END ANCHORAGE(b) SteelEnds of Joist Girders resting on steel supports shall beattached thereto with a minimum of two 1/4 inch (6 millmeters)fillet welds 2 inches (51 millmeters) long, or with two 3/4 inch(19 millimeters) ASTM – A307 bolts, or the equivalent. In steelframes, bearing seats for Joist Girders shall be fabricated toallow for field bolting.(c) UpliftWhere uplift forces are a design consideration, roof JoistGirders shall be anchored to resist such forces (Refer toSection 1004.9 Uplift).SEAoT State Conference November 6-8, 2008 Houston TX SEAoT - 66
P n = 2 M p L yl / aASD Design ProcedureWhere:P n = Nominal uplift capacityM p = Plastic moment capacity of plate perunit length= F y ZZ = t 2 / 4L yl = Length of yield linea = 2.3 tΩ = 1.67 (AISC-ASD safety factor forbending)P n /Ω = Allowable uplift strengthSEAoT State Conference November 6-8, 2008 Houston TX SEAoT - 67
