Anchors Near Pour-Strip Joint

Anchors Near Pour-Strip Joint

Anchors Near Pour-Strip Joint

(OP)
I am designing some post-installed anchors for a steel bracket that will be located near or perhaps straddling a joint in a concrete slab. The joint is between the main slab-on-grade and the pour-strip next to the tilt up walls, with rebar thru the joint. This is not a control joint and it is tight.

Obviously, treating the joint as a "free edge" is the conservative approach. Is this commonly treated as a free edge? Or perhaps can it be regarded as a "crack"? The joint lacks the irregularity of a "crack", but I was wondering if anyone would treat it as a crack in where designing the anchors for cracked concrete in the vicinity would be sufficient.

Your thoughts would be appreciated.

RE: Anchors Near Pour-Strip Joint

I queried something silimilar to hilti a while back. while they said they do not have specific tests they thought my proposal of treating it as cintinuous and a cracked section to be reasonable

RE: Anchors Near Pour-Strip Joint

As the concrete ages, the joint will open slightly even though rebar is there. If the gap in the joint is expected to exceed 0.012", then the cracked section consideration should not be used and the free edge should be used.

RE: Anchors Near Pour-Strip Joint

A construction joint such as you described is a crack, just a straight one.

Thank you for your responses. It is good to know that this type of joint isn't automatically regarded as a fee edge.
