Robert - Thanks for the information. Wish I would have spoken with you a couple of months ago.
I do have a problem with the statement "these type of adhesives are....specifically not recomended for underwater or water filled holes". Unfortunately, the manufacturers (Epcon A7 and Simpson AT)...
Clefcon,
We roughened some of the holes with a percussion drill. Didn't improve results.
After observing the pulled out bolts with adhesive still on them, the problem was clearly an issue of shrinkage - not lack of bonding. For most of these failed bolts - there was NO bonding, because the...
New to the forum here and wanted to pass along some problems I had with the performance of adhesive anchors installed underwater.
I recently was involved in a project where we mounted a steel structure to the vertical face of a dam underwater in approx. 40F temp water. The structure was...
Is there a basis for looking at the net area due to bolt holes in a compression member? To compound matters, these are slip-critical bolts. The holes would be located a significant distance from the ends of the compression member.
Intuitively I would assume that any localized stress increase...
Dave,
The slab does in fact extend beyond the RC beam. To give you a little background - because of the relatively complex loading (circular loading pattern with 8 bearing pads) and complex slab-column-circular wall system - I have modeled using STAAD. To my knowledge (this is my first floor...
I have run into a situation on a cantilevered slab that monolithically ties into a RC beam. The proposed loading will result in an applied torsion that exceeds the torsion capacity of the RC beam. The RC beam does not have the tied (torsion resisting) stirrups, so I analyzed the capacity of...
