LEAP Bridge Concrete: Prestressed Box Beam End Block

Hi Eric,

Please go to Geometry TAB --> Cross Section layout
In this window user can create varying cross section along the length of the box girder.
As per your project requirement you need 2 ft end block which will act like Diaphragm at the ends of the boc girder.
So please click on Diaphragm In and Diaphragm Out and input the width of the end block at both the ends.

This will help in the shear capacity and end stresses.

Please see the screenshots for more information.

Please let me know if this is the information you are looking for.

Please check the Bentley Communities link for additional information.

I hope it helps.

Thanks & Regards,

Hello Vinay, thank you for taking the time to respond. It looks like the images you are showing are from CIP RC/PT Girder, I am using Precast/Precast Girder. Some images from my model are below, and I do not see the same options, but I may be missing something. Thank you for your time,

Hi Eric ,

Sorry for the miscommunication as i read it as PT box girder.

For Prestressed Box Section/Girder in Conspan there is not option to customize the section along the length of the span 

and the cross section remains constant.

I apologize for the inconvenience.

I hope it helps.

Thanks & Regards,

Vinay

Vinay,

Thank you for the clarification!

You are welcome Eric
