Hi
I m trying to change the default value of min. haunch thickness of U40 beam to 2.0 in from 0 in.
The default value setup in the beam library is 0.0 in. It seems to be wrong.
Please let me know how I could modify it.
Thanks

The U40, and others, are defined in a shared library. You can’t change it because it would be changed for everyone. Make a copy of the beam, change the settings you are interested in, and select the new beam into your model.
If you think there is an error in the published libraries, please contact the library publisher so they can fix it.
Thanks Rick, I wanted to know if the haunch calcs for Ubeam girders are calculated correctly. I did a hand calculation and caught this mistake in PGSuper.
If you think the calculations are incorrect, please share your calculations and we will look into it. We believe the haunch calculation procedures are correct and comply with WSDOT and TxDOT standards as well as the calculations presented in the PCI Bridge Geometry Manual.
I want to upload the PGSuper file but I do not know if it is possible in this forum.
I m getting an slab offset of 9.75' which I think is wrong as the min. haunch thickness at CL of BRG is 2" plus the 8.5" slab thickness.
The TxDOT U beams do not have a minimum haunch depth at the CL bearing per the Bridge Design Manual. The 2" would only be required if the precast panels are taken to the end of the beam, like is shown on sheet 4 of the PCP standard. If you want to design to make this allowance, then you need to copy the beam in the library and change the haaunch parameters in the copied beam.

I think you need to go back to your original post in the thread to upload a file.
If that doesn't work, you can send it to me directly along with calculations that demonstrate what you think is incorrect.
