Hello,
In LBS I have a preliminary girder design that meets code checks, no flags in "Summary - Under Design" report. I decided to try the Design Optimization tool in Member Definition to see if there were any suggestions I would like to incorporate. What I ended up getting was a few isolated locations that showed my area of provided steel being less than what was required... under designed. Is there an explanation for why my design meets code check and AASHTO equations at a location but the design optimization report shows it as under designed?
Also, in Member definition the diagram shows provided vs. required steel. In my model I am seeing strange As required distribution that instead of a gradual increase in As required that peaks a the pier the diagram shows As required that jumps at my section change point and is level through the pier until it drops again at my next section change point.
The first Member Definition window shows my design. The second Member Definition shows flange thicknesses reduced to 0.1" so the As required is visible.
Thanks!
You have to be careful with the reports. I have had summary reports that said everything was fine and when I went into the detailed reports things were failing. Also, I've had summary reports saying things were failing but when i went into the detailed reports they were fine.
