January 21, 2020 - WSDOT Engineers have identified a bug for U-Beams in PGSplice 4.1.0-4.1.5. Secondary Post Tensioning effects are not computed correctly for all stressing stages for U-Beams.
When there are multiple stages for PT for U-Beams, the secondary effects of PT are not computed for the later stages. Investigation of the source code for generating the load revealed that the input number of ducts, not the actual number of ducts is used resulting in 1/2 of the actual PS force.
This problem only affects spliced U Beams. We recommend that you update to version 4.1.6 immediately if you are working on this type of project.
