uckling <strong>of</strong> the plate under service loads <strong>and</strong> if this results in audible banging or othernegative effects.3. The materials allowed for the web plate should explicitly include ASTM A1011 SSGrades 30 <strong>and</strong> 33. These materials have greater ductility than ASTM A1011 HSLASGrade 55 which is already allowed.4. There are three methods presented for designing VBE’s that give significantly differentresults. These variations should be reconciled.5. The method for designing VBE’s called linear elastic computer programs <strong>and</strong> capacitydesign concept, considers axial forces amplified by Ω o , but moments due to web plateyielding in panels above or plastic hinging <strong>of</strong> the HBE’s is ignored. This appearsinconsistent with the intent <strong>of</strong> the provisions, which is that VBE’s remain elastic whilethe web plate yields.6. Strong column / weak beam design checks are specified to be carried out withoutconsidering web plate tension. Since a large portion <strong>of</strong> the axial forces <strong>and</strong> bendingmoments in the columns will be caused by web plate tension, this design check does notlimit the plastic hinging to HBE’s.ReferencesAmerican Institute <strong>of</strong> <strong>Steel</strong> <strong>Construction</strong> 2005.
