Loading 1.2.1 HILTI ANCHOR CHANNEL PORTFOLIO AT A GLANCE Hilti’s simplified and value engineered cast-in anchor channel system portfolio, in conjunction with PROFIS Anchor Channel, helps designers to easily provide model code compliant and cost-effective anchor channel system solutions. HAC's standard portfolio covers most of the extreme project conditions.

1. Anchor Channel Systems 2. HAC Portfolio 3. HAC Applications HAC and HAC-T Hilti Anchor Channels with rounded head anchors are characterized by been the most cost-effective anchor channel type. Additionally, due to its lighter weight, they are generally easier to install than anchor channels with reinforcing bars. These are excellent anchor channel systems with optimized steel components. The HAC portfolio allows for a gradual increase in performance.

1. Anchor Channel Systems 2. HAC Portfolio 3. HAC Applications Hilti Anchor Channel with the new rebar edge confinement plate (HAC EDGE) is a solution that offers superior concrete edge breakout performance in shear. HAC EDGE changes the traditional concept of anchor channels with welded reinforcing bars.

Loading HBC-T For tension, perpendicular and longitudinal shear loads Hilti Channel Bolts (HBC and HBC-T) are part of the cast-in anchor channel system. HBC come in a variety of diameters, grades, and corrosion protection. The T-bolt head shape works with all four different channel HAC sizes (HAC-40, HAC-50, HAC-60, and HAC-70) simplifying logistical management on the jobsite.

The possibility of cracks intersecting the anchor location can therefore be assumed to be highly probable, even if the original anchoring location was assumed to be uncracked, as indicated.

During seismic events, anchors used to connect structural and non-structural elements to concrete are subjected to cyclic tension and cyclic shear loads. Cycling loads may induce additional cracking that can ultimately reduce the concrete capacity of the anchor. This effect is reflected in figure 6.3.1.

Loading Calculations Step 3: Determination of worst tolerance Please note that the t-bolt forces are applied all along the channel length and the forces at anchors are determined. Then the worst case utilization report will be printed out in profis anchor channel software. Therefore the bracket can be located any where along the available channel length.

Base material Calculations The highest loaded anchor element in tension does not always control the anchor channel design in tension. The highest utilization, defined by the parameter (Nua,total / φNn) controls the design. Therefore, the tension design strengths must be calculated for each anchor element and checked against the total factored tension load acting on that element.
