Verifying Fatigue Stresses in Leap Bridge Steel

Benji Michael Chit Khin — Thu, 24 Mar 2022 16:56:12 GMT

Hi I have a question regarding Fatigue stresses in Leap Bridge Steel.

I have several locations along the girder that fatigue is the controlling design.

Based on the calculations reported, it appears that Leap Steel is using non composite properties to calculate the fatigue stress rather than the composite properties which is causing a higher stress to be reported than it should. The girder itself is being reported as composite and has the composite values calculated correctly.

I saw a similar question was posted about this a few years ago and wondering if this has been resolved?

Thanks

Michael

Hello there, I'm receiving an error when trying to model stiffeners with an offset from bottom. The error and the stiffners that I'm aiming to model is shown.

Thanks

I get the above error when trying to start an OBD project off in Projectwise. I found a document the Iowa DOT uses for setting up in bridges and followed that after my first failure. Unfortunately, I continue to get errors. the latest error is what is in the subject. Can anyone provide some guidance on what I should be doing to set projects up?

Some additional information... I get to OBM an then the error occurs.

TIA

Josh
