Friction-Grip bolted connections for structural glass

Friction-Grip bolted connections for structural glass

(OP)
Does any one know how to calculate the strength of friction-grip bolts for connection to structural glass?

RE: Friction-Grip bolted connections for structural glass

I doubt this would work, glass creeps and thus would lose friction.

My initial reaction was that friction grip bolting wouldn't be effective as the available friction between glass and steel would be low. Also there's probably a risk of cracking when torqueing up the bolt, I'd be a lot happier with snug tightened.
With reference to your attachment, there's no mention of friction grip bolting there.

Take a look at the enclosed info, specifically the last article as it relates to the use of friction-grip bolts for this purpose.The info on the first page relates to the design of high strength friction-grip bolts, but I am not sure if it applies to structural glasses.

RE: Friction-Grip bolted connections for structural glass

Structural glass is not something most of us deal with.  It is in the realm of facade engineering, and is still developing.  You might try the Glass Engineering Forum on this site, but I don't know how active that is.  Otherwise, why not see if Pilkington has the information you need?

RE: Friction-Grip bolted connections for structural glass

By reading the attachment I assume there is more to it than just a bolt. There is mention of overcoming the creep inherent in laminated glass and also of fibre washers.
As suggested above contact a manufacturer.

Thanks for the feedback guys, as suggested I am probably better off contacting the manufacturer, as this is not our typicall structural problem.
