For custom sections of lumber beams from the “Beam and Stringer” classification listed in 4D , the bending strength Fb shown in the Factors table of the Additional Data was the one for the “Post and Timber” grades from Table 4D , However, the resulting moment resistance Fb' value shown in the Force vs Resistance table was derived from the correct “Post and timber” Fb, and this was the value used for design. This is therefore a display issue only, which has been corrected.
For columns, the lateral deflection values displayed in the Beam Graphs were the metric mm equivalent to a displacement in inches, even when imperial is the unit system selected and "in" is shown on the diagram. That is, a deflection of .1" was showing up as 2.54". This has been corrected.
When metric units are selected, the tributary width for area loads shown in the loads tables in the analysis and design results is expressed in inches, to the closest whole inch. This has been corrected.
If there are no loads on the member that would lead to live deflection, the program no longer outputs a line showing the critical load combination for this case. Previously it was showing the first load combination in the list, leading to paradoxical output like self-weight-only being critical for live deflection, because there were no live loads at all.
In the "Critical load combinations" section of the Design Results, and in the Deflection Analysis Diagram, the load combination 0.5D + L arising from the option in Load view for IBC 2009 Table 1604.3 note (d) is presented as D + 0.5L.
This combination also appears for live-only deflection, giving the impression that only half the live load is included.
This had no effect on design; it is just a reporting error that has been corrected.
