- Tensile Load
-
The component of the resultant load, designated "N" by HAP,
on an anchor that is parallel to the longitudinal axis of the anchor.
Note that these loads can be (+) for tension and (-) for compression.
- Shear Load
-
The component of the resultant load, designated "V" by HAP,
on an anchor that is perpendicular to the longitudinal axis
of the anchor. Note that these loads can be (+) or (-)
depending on their direction.
- Resultant
-
The combined (resultant) force from the shear
and tension components of load on an anchor.
- Concrete Compressive Strength
-
Concrete compressive strength is used to describe the specific
concrete stress at which a concrete cylinder fails under
compressive loading, as tested pursuant to ASTM C 39.
All allowable loads used by HAP are based on testing in unreinforced concrete.
If a concrete strength of greater than 6000 psi is entered into HAP,
this value is reduced to 6000 psi. If a concrete strength of less than
2000 psi is entered, an error message is generated.
- Depth of Embedment
- The depth of embedment is the distance from the surface of
the concrete to the bottom of the installed anchor. The depth
of embedment can be critical in determining the load-bearing
capacity of an anchor. HAP uses linear interpolation to calculate
anticipated load bearing capacity between an anchor's minimum
and maximum embedment depth when specified. However,
HAP does not extrapolate load bearing capacities when less
than the minimum or more than the maximum embedment depths are
specified. That is, for embedment depths that are greater than
the maximum tested depth, the maximum tested depth is used; and
for embedment depths that are less than the minimum tested depth,
an error message is generated.
- Edge Distance
- Edge distance (c) is the measure between the anchor
centerline and the free edge of the concrete or masonry
member into which the anchor is installed. Critical edge
distance (ccr) is the minimum edge distance at which
the allowable load capacity of an anchor is obtained.
Minimum edge distance (cmin) is the closest edge distance
recommended, which will also create a reduction in
the allowable load capacity of the anchor.
- Anchor Spacing
- Anchor spacing (s) is the measure between anchors
centerline- to-centerline distance. Critical spacing (scr)
is the minimum anchor spacing distance at which the full
allowable load capacity of an anchor is obtained without
influence of neighboring anchors. Minimum spacing (smin)
is the closest anchor spacing recommended, which will
also create a reduction in the allowable load capacity
of the anchor.
- Anchor Plate Thickness
- The anchor plate thickness is the thickness of the part being fastened.
