Hello. Can adhesive anchors be installed in the same exact location as a previously installed adhesive anchor after the extraction of the existing anchor? A design I am reviewing is showing an existing 1-1/4 adhesive anchor with 12 embed, which is going to be extracted (not sure how) and a new 1-1/4 adhesive (HY-200) anchor ...

Is it possible to analyze HDA undercut anchors using the Hilti Profis software?

I am looking for an epoxy anchor to anchor the legs of a steel treatment vessel. The bolt diameter needs to be 1-1/4 and the tension strength needs to be 20,000 lbs. What would the required embedment in new 4,000 psi concrete. What would be the specified model of this bolt installation.

What is the required installation torque for a KH-EZ C SS 316 1/4 anchor into lightweight concrete

Do all KH-EZ screw anchors require a welded washer plate or other means to transfer shear (not through bearing) to the fixture since the required fixture hole diameter is 1/8 larger (oversized) than the anchor diameter ? Applicable to other post-installed anchors that require an oversized fixture hole.

*See attached image. When comparing the drill diameter while drilling through baseplates (df1), to AISC 360 Table J3.3, it appears that every hole will fall into the oversized category. Do the oversized holes require weld washers to transfer shear? Has the anchor rod and epoxy system been tested for shear transfer with the ...

A rated wall extends 30' up to underside of roof deck. It is penetrated by the end of about 25 steel trusses, and a built out frame would be about 16x20. The project is a large factory in NV. The client is in VE mode already so is searching for the cost effective solution.

We used KB TZ2's to anchor a fire pump controller to floor. The Controller manufacturer installation manual states to use a Grade 5 bolt. Are the KB TZ's equal to or stronger than a Grade 5 bolt?

what are the minimum and maximum hole diameters for use with the HILTI epoxy adhesive system

Are the minimum concrete thickness listed for the Kwik-Bolt TZ2 based on the nominal design concrete thickness, or the actual concrete thickness. For example, for a nominal design 8 concrete slab, ACI tolerances would allow the actual condition to vary down to 7 3/4 minimum. Any chance this 1/4 difference was considered in the...
