The KD factors for shear and moment design calculated using O86 4.3.2.3 for long term loads greater than standard term loads, could be retrieving the wrong moment and shear components by load type for use in determining the effect of the loading on each span for each criterion. This occurs in for the following situations, which have been corrected:
Different Load Profiles on Beam
The shear and moment values at a location on the beam may be taken from a point that is shifted slightly on the beam in the case where different load combinations contain loads with different profiles.
Dead Loads due to Soil in Patterned Combinations
When dead loads due to soil are present with patterned load combinations the dead soil component of the moment was being treated as live for the moment KD calculation.
Shear KD for Pattern Combinations
For patterned live load combinations (L_, L__, etc) with dead loads present, the spans without the live pattern load were using zero for the live shear component for shear KD.
Sustained Live for Pattern Combinations
For patterned live plus sustained live load combinations, on the spans without the patterned loads, the sustained live component of the shear was being included in the live component.
Live Loads at the End of Pattern Spans
For patterned live plus sustained live load combinations, at the end of spans without the patterned loads, the live and sustained live components of the moment for moment KD were sometimes using equal but opposite signed values when they should actually both be using zero.
Eccentric Axial Loads
For columns with eccentric axial loads with dead, live, and live sustained shear components, the live and sustained live shear values were both zero for the 1.25D + 1.5L + 1.5Ls load combination. For load combinations that also include snow, the live, live sustained and snow components are non-zero but unpredictably incorrect.
