Cantilevered Bolts

[Subject Prev][Subject Next][Thread Prev][Thread Next]

I have a project that requires the use of cantilevered bolts (to clear a façade that the contractor wont remove/rework)

They will be attached via drill and epoxy to a concrete beam that is 6” from the application of load. 

How do I design a drill and epoxy situation for an embedded pole type bending force?

I’m thinking that I would figure the design shear the same way that I would find the max stress on a weld – f = 6M/(L^2), where L would be the embedment in this case, and use f+V as my design shear just as I would for a normal non-cantilevered bolt.  Does this sound correct, or does anyone know of a more appropriate method?


Any other potential issues?
