Load Combination Descriptors
In the Analysis Diagram, the Analysis Report, and the Additional Data section of the Design Check report load combinations descriptors have changed as follows:
Use L+0.5D for deflection
The old string was D+L; it has been changed to .5D+L
.7W for C&C wind load
D+W is changed to D+.7W
6D+W is changed to .6D + .7W.
D+.75(L+W) is changed to D+.75(L+.7W).
Analysis Diagrams
Previously, when displaying results for a particular load combination, the load combination is shown in the list box for screen display and at the head of the printed report. Each diagram does not repeat the load combination it is depicting.
Now, if the load combination for deflection is different than the load combination used to calculate reaction, shear or bending, because of the IBC-specific settings, then for the deflection results only, the combination used for deflection is output.
Analysis Reports
Two notes have been added to the table to indicate the IBC load combinations in use:
Use L+0.5D for deflection
If this setting has been selected, and there is a D + L load combination, an asterisk is placed by the load combination and the following note appears saying
* 0.5D + for deflection: IBC Table 1604.3d
.7W for C&C wind load
If the setting has been selected a note appears that says
Wind loads are C&C = 0.7W for deflection: IBC Table 1604.3f
Note that this message appears even if there are no wind loads on the member.
