I'm trying to run a load rating on a 1978 prestressed concrete "Channel Section". Although I can't find this type of section labeled in the girder library, I am able to replicate the geometry of this section by modifying the "Double T" shape in the girder library - however PGSuper will not allow my to place the pre-stressing strands as they were constructed -- I get an error message telling my that I can't place strands in the narrowest section of the web. Is there anyway I can work around these design checks? Please see the attached JPG to see the cross section, strand layout and rebar layout of the beam I am trying to model. Thanks
