The following improvements have been made to the Design Check Calculation Sheet report:
Design Ratios as a Percentage (v9 - Change 154)
A Preference Setting has been added to allow you to show the design ratio in the Force vs. Resistance output as a percentage, .e.g. 87.1 %, rather than a ratio, e.g. 0.87.
The default value for the setting is to continue showing the ratios as a decimal value as in previous versions of the program.
Note that there is 10 times greater precision in reporting the design ratio, so that when it is for example 1.002, the report will show a failed design of 100.2% when percentage is chosen, but a passing design of 1.00 when ratio is chosen.
Units Column in Force vs. Resistance Table (v9 - Feature 198)
Instead of listing the various physical units, like lbs, kN and plf, in the heading to the table of the Design Check output, the program now lists the unit used for each design criterion in a new column in the table, thus associating the unit used with the design criterion.
Post/Stringer Grade in Materials Specification (v9 - Feature 67)
The program now indicates in the third line of the materials specification in the Design check output whether the member uses the Beam and Stringer or the Post and Timber strength properties from Tables 5.3.1C and 5.3.1D respectively. The definitions based on section dimensions are found in notes (1) of these tables.
If a custom section is two thin to be in either category, then no category is output and a warning appears in the output. Refer to Bug 2797 to changes made to the warning messages that can appear.
Warnings for Incorrect Lumber Sizes (v9 - Bug 2797)
A warning did not appear if you entered a custom size for a lumber database that is in fact a timber size according to CSA O86 Table 5.31C/D, note 1. However, a warning does appear when the reverse is true.
For some cases, such as bending, the lumber sizes are stronger, and for some such as shear the timber sizes are stronger, so there is always a non-conservative error if the wrong grade properties are used. A warning is now shown in both cases.
Load Combinations for Bearing Design (v9 - Change 167)
The load combinations for bearing design are now spelled out in full in the Additional Data section, similar to other load combinations for other design criteria.
1 - Pf/Pe Line in Additional Data When Negative (v9 - Change 148)
When Pf/Pe in CSA O86 5.5.10 is greater than 1.0 so the moment magnification factor for combined bending and axial loads is negative, thus nonsensical, the program no longer shows the line in additional data that wrongly says that the factor is 1.0.
In this case, the factor is in fact not calculated and the Analysis / Design table shows Pf/Pe as being a failure.
E05 Value in Additional Data (v9 - Feature 174)
The program now outputs a line in the Factors table in the Additional Data section of the Design Check output for the E05 value used for the Euler buckling load in O86 5.5.10 for combined axial and bending and for the slenderness factor in 5.5.6.2.4 for compressive resistance parallel to the grain. This applies to columns subject either to compression or combined loading.
Multi-ply Custom Section EI in Additional Data (v9 - Bug 2729)
The EI value output in the Additional Data section for multi-ply custom section sizes was showing the EI value for all plies combined, not per ply as indicated in the note. This has been corrected.
Failure Warning for Axial Plus Bending Criterion with Eccentric Axial Loads (v9 - Bug 2727)
Starting with version 8.2 of the program, the failure message for the axial plus bending design criterion was not showing up warning section of the Design Check output when a column with no lateral loads but eccentric axial loads failed for this criterion. This has been corrected.
Design Code Clause Reference for Glulam Point Load Bearing (v9 - Bug 2846)
In the note under the bearing design table and in the design notes, if point loads at a support governs for bearing design of glulam members, the program now references the glulam clauses 6.5.9.2 and 6.5.9.3 instead of the sawn lumber clauses 5.5.7.2 and 5.5.7.3.
Support vs. Supports in Bearing Table (v9 - Change 168)
In Reactions and Bearing table, under Resistance, Supports has been changed to Support for consistency with other output.
