I have a beam framing into an existing column. I have ran my loads based on two conditions. The first part of the PDF shows an infinite edge distance parallel with the shear load, and the analysis passed. For the second condition, instead of an infinite edge distance, I put in 100" in each direction, and the analysis failed. I can put 200" in there, and the same percentage of failure applies. I do so in ACI 318-19 R17.7.2.1 that when anchors are far from the edge, breakout will not control. So I'm assuming that is why the first pdf with infinite edge distance did not calculate edge breakout failure. What I am questioning is why the program diverts to failure when you put a large edge value in there. It acts like it takes ca1 as the edge distance perpendicular to the load, which I don't think should be the case. Should I just ignore the second analysis, and make sure for further calculations to never put an edge distance in that is large? My next question would be, what determines a large distance?
FYI: I tried uploading
Hi Alex,
PROFIS Engineering is limited to a strict interpretation of the ACI 318 Chapter 17 anchoring-to-concrete provisions. Thus, the software is unable to determine on its own if a large edge distance should be considered finite or infinite. If an edge distance is defined in the software, PROFIS Engineering will evaluate the appropriate ACI 318 provisions accordingly. Whether or not to consider an edge distance large enough to be considered infinite is typically based on the engineer’s interpretation of the ACI provisions.
