Dear Engineers,
Greetings for all structural engineers in the world. I'm a bridge engineer from the Philippines and currently connected in a consulting firm. I'm using Leap Bridge Concrete for less than a month and find out that it's a very powerful bridge software. I'm wondering if there is a post-tensioning option for AASHTO I Girder in the latest Leap Bridge Concrete v17. Can you help me in finding for solution?
Thank you.
Regards,

Hi ,
There is no option for Post tensioning option for AASHTO I Girder in LBC .
But there is a workaround solution for this issue . In LBC there is a module to design POST TENSIONING Box girder, T beams and Slabs .
1) In ABC wizard user needs to select Post Tensioned CIP Box and Boxes option and select the number of span as 1 and input Interior Girders as 1.
2) Click Next and Next and model the bridge .
3) Then go to Superstructure TAB and click on CIP RC/PT Girder and then in the new window click on Geometry TAB and then click on Cross Section button.
4) In the Cross Section layout window click on Section button and in the new window get rid of Exterior girders and modify the width, Depth and other important information and click OK. These modification can be done as per AASHTO standards
5) Then the user should be able to see I girder in the section .
In this way the user can design only one girder at a time and it is not possible to design multiple girders at the same time.
Please see the attached screenshots for more information
