The tests follow AC232 testing guidelines.
Refer to anchor channel theory for further
clarification. Please refer table 2.3.3.1 for
strength values. l d is in accordance ACI318-11; chapter 12.2
is used. The stress in rebar is found by
isolating (f y =) σ d in the equation as shown
below.
ΦN sc > N aua
The tests follow AC232 testing guidelines.
Refer to anchor channel theory for further
clarification. Please refer table 2.3.3.1 for
strength values.
IMPORTANT! Failure analysis modes evaluated follow ACI 318-14, chapter 17. This DOES NOT include evaluating the base material (e.g. edge-of-slab)
capacity to resist compressive forces generated by the fixture. The engineer must ALWAYS verify the base material (e.g. edge-of-slab) design is capable
of resisting the applied loading.
For additional information, please contact Hilti at [email protected]
In cases where ℓ d is provided (ℓ d,prov ), the
nominal pull-out strength of the rebar (N p,R )
is as follows:
ΦN sa > N aua
The tests follow AC232 testing guidelines.

If a rebar provides the required
development length, the rebar will yield
before it is pulled-out of the concrete. In
situations where the force at the rebar is
less than its yield strength, ACI 318 allows
reduction the excess reinforcement.

The ACI concept of development length
is based on the attainable average bond
stress over the length of embedment of
the reinforcement.
