Problem:

On the Code stress tab some of the combination results has the wrong units, example: from Result> Code Stresses> note units for PE Ring Def are inches.

 

However, using Results> Grids or Results> output report, the values are in a clumn where the units are shown as PSI:

 

 

Why?

Answer:

The real estate of the Results grids only provides enough room for so many columns. As a result some columns are used for double duty.

Example: combinations like Ring Defl-HDPE are a code stress combination with the units "inches", however these results are placed on the Code Stresses tab of the results grid in the Stress & Allowable columns that are labeled  with "PSI" units. This is correct. Again, instead of having a set of column for Stress & Allowable in "Inches" and another set of columns for Stress & Allowable in "PSI", there is only one set of columns that uses the units "PSI". The user should know which combinations are measured in a different unit when looking at the Results Grid. Otherwise, see the output report.

When reviewing the Code Compliance sub section of the output report, see that the header at the top of each page for the type of load and associated units.

 

Note that the Code Stress and Code Allow. column results could be one of 3 choices: Stress in "psi", Deflection in "inches", or Flotation in "lb/ft". Again the user should understand what category a specific code stress combination will fall into: Stress, Deflection, or Flotation, and know to apply the correct units to the results.

As shown in the image above, is an example of the possibilities for the code stress and allowable columns:

Ring Defl-HDPE{1} = 0.38 inches, 0.70 inches
Flotation-HDPE{1} =  66.7 lb/ft, 1909.0 lb/ft
Amb to T1-HDPE{1} = 38.3 psi, 1100.0 psi

And Respective values shown in the Results Grid:

Note: Again, the columns are labeled with PSI, but the actual units are understood to be as shown in the output report.
