Version 3.3.5 Enhancements & Modifications
February 1, 2012
- Seismic Loading –
The previous version inadvertently omitted adding the
seismic occasional loading onto the operating case
when non-linear restraints were found wthin the piping
model. This release corrects that ommision.
- SIF for Welding Tee –
In recent releases of the B31.1 and B31.3 piping codes
the default SIF for a welding tee has included a
flexibility characteristic of 3.1 T/r2. While
the included notes allowed for a value of 4.4 T/r2
when ce4rtain values of crothch radius and crothch
thickness were prsent, we have opted to use the defout
3.1 value which gives a more conservaitve SIF. The
default in B31.8, B31.1 and B31.5 continues to be the
4.4 value which we will continue to use.
As always, should the user wish to modify the SIF,
entering the actual value into the branch dialog will
override the automic calculation.
- Demostration Mode – The
DEMO mode for the precious version erroneously gave a
"Expriration Date Reached" message after one had done
a calculation with a demonstration piping system.
This has been corrected.
