Acute and obtuse corners
Please refer section 9.2.7 for details on analyzing the obtuse and acute angle corner with single anchor HAC EDGE channel at
the corner. Also refer 9.6.3 and 9.6.4 on details for analyzes and all the failure modes and interaction that needed to be taken into
consideration.
9.6.5 — HAC (T) EDGE, HAC (T) EDGE LITE AND HAC S (T) EDGE
DESIGN: TOP AND BOTTOM OF SLAB OUTSIDE CORNER WITH
PAIR OF ANCHOR CHANNELS
Corner Rebar Top of Slab (EDGE C)
In order to install two EDGE front plates close to an edge some
modifications to the geometry of the product are needed.
Indeed, the rebar location of one EDGE Plate (EDGE C) needs
to be lower, in order to avoid clashing with the rebars of the
adjacnet corner channel. This is illustrated in Figure 9.6.5.1.
For this application, one element is a standard EDGE and the
second is the so-called Corner Rebar Top of Slab (EDGE C)
front plate.
The EDGE C front plate is 20 mm higher and has the rebar 14 mm
deeper in order to cross those of the other EDGE element. The
thickness of the plate is increased to 6 mm instead of 5, in order to
resist the bending moment due to the larger lever arm. The other
geometrical dimensions, as well as the position and number of the
rebars remains the same as described in chapter 02.
The vertical distance of the rebar center point from the concrete
surface is for the EDGE C: e
r
= h
ch
+ 3d/2 + 2 [mm]
Refer Figure 9.6.5.1 for the description. This e
R
will effect the
magnitude of tension force that the rebars will experience
as described below. Refer Figure 9.6.5.2 for the example of
determining the rebar forces
It will not be possible to select a EDGE C front plate as stand-
alone in Profis. A EDGE C will be automatically adopted when
the corner is activated on the second edge.

SOFTWARE
PROFIS Anchor Channel allows users to quickly and accurately model anchor channel system
applications. Through a simple, user-friendly interface, the verification of 20 anchor channel failure
modes and 5 interaction equations can be done in seconds.
PROFIS Anchor Channel allows users to design anchor channels with anchor reinforcement.
Moreover, the so called anchor channels with “rebars” (HAC CRFoS U and HAC EDGE) are available.
The software also allows users to design even the most complex applications such as seismic,
corners, and applications in lightweight concrete and thin slabs.
