New AISC LRFD Specification Inconsistency for Element Shear Yield?

[tslewis]

Hmmm

has anyone noticed that the LRFD reduciton factor for "strength of elements in Shear - shear yielding of element" - Chapter J - has been increased from 0.9 to 1 in the 2005 AISC steel specifications?

New 2005 LRFD Specifications - EQ J4-3 LRFD factor = 1

Old LRFD 3rd Edition - EQ J5-3 LRFD factor = 0.9

thslewis,

please see the commentary to AISC 360-2005, on page 351, they were "recalibrating" the LRFD provisions a little to make them show a safety factor that more closely matches the one in ASD.
