The abutment cap is failing in negative moment at the exterior drilled shaft location, like shown on the image below:
But the moment strength envelope is showing otherwise:
There is also an odd decrease of negative moment capacity on the circled red region.
Any help would be greatly appreciate it.
Try to extend the bar/ increase the bar size or hook the bar and see if it works .
That will increase the flexure capacity of the cap, but my question is related to the discrepancy of the strength envelope diagram to the cap results report. The strength envelope diagram shows clearly that the capacity is good, but the report says otherwise. Also, the dip of negative moment capacity in the area circled in red, does not make sense.
Please email me the file so that I can test it . Please let me know the version you are working on.
I just emailed you the file.
The version I'm using is:
