Regardless of the loading, anchor bolt type or base plate size and thickness, the minimum edge distance to face of stem wall controls my design. Min Edge Distance and spacing between anchor bolts dictates the concrete wall thickness. for any 1/2 diameter A.B. min edge distance and min spacing is 4. This makes 12 wide concrete...

i am installing #4 rebar and using HY-200 epoxy, what size hole would i have to drill??

Our project is in for approval with the California Divison of the State Architect (DSA) and they have have a comment that we need to address. In particular, what is the correct embedment for a Hilti 0.157 shot pin into the bottom flange of a steel I-Beam?

We have a contractor who did not get special inspection for Hilti HY270 anchors during installation. They have asked if the anchors can be checked using torque versus a traditional pull test. We do not see any information that notes this as an acceptable test method for testing the tension on the bolts. Does Hilti have any ...

Have the issues between RISA and Profis been resolved where imports are now successful?

While doing a baseplate design in profis, shear lug was designed to be used in the design due to the high shear values. However, Profis's biggest shear lug is a 12 wide and 1 thick shear lug and this did not meet the needs of demand. For a higher capacity, a higher effective bearing area is required. The effective bearing area...

Can you supply a head of wall joint detail for an 8 cmu (2 hour rated) wall to the underside of metal roof panel?

I am designing a connection between a 2x material and a 1/2 thick steel plate. I can not find any information on the shear strength of the fastener nor the recommended fastener to use for this application. What would be ideal and recommended per Hilti?

I am using the above to adhere Hilti HAS Anchor Rod 6-1/2 L into concrete at an embed of 5. How many uses can I get?

My company recently updated our drilling standards and will now be requiring diamond cored holes for certain conditions. If possible would you be able to elaborate on how the core breaks away from the remaining concrete after drilling? I will be giving a presentation on the updated construction methods to our contractors and I...
