Q

The _____________ is the highest load a design engineer will subject the anchor to during normal use

A

Allowable working load

26
Q

The force cutting across the anchor in a direction perpendicular to its length is the _____ force.

A

Shear

27
Q

When tension and shear act at the same time on an anchor, a _____ force results.

A

Combined

28
Q

A shear load acting at a distance from the base material surface is defined as a _____ force.

A

Bending

29
Q

The force trying to pull the anchor straight out of the hole is the _____ force.

A

Tension

30
Q

______ ________ occurs when the anchor material fails or the adhesive bond with the base material fails

A

Anchor Failure

31
Q

_______ _______ occurs due to edge failure, spalling of the concrete around the anchor, or splitting.

A

Concrete Failure

32
Q

The load applied to an anchor may exceed the anchor material’s ultimate load. This typically happens with anchors that are deeply embedded relative to their diameter, or with high, repetitive (fatigue) loading.

A

Anchor Material Failure

33
Q

______ _______ occurs when the applied load is greater than the concrete’s tensile strength.

A

Cone Failure

34
Q

If an anchor is placed and loaded in concrete with insufficient thickness, width, or strength, the base material may split.

A

Concrete Splitting

35
Q

The weakest aspect of the anchoring system determines the failure mode

A

Weakest Aspect

36
Q

represents the distance from the surface of the base material to the deepest part of the anchor after it has been driven into the hole, but before it has expanded.

A

Depth of embedment

37
Q

To obtain the ultimate load bearing capacity of any anchor, the cone of influence must not overlap the edge. If this occurs, the volume of base material being used is reduced.In order to be reasonably certain that the edge will not break away when the anchor is being set, the minimum specified distance from the edge must be observed.

A

Edge Distance

38
Q

The closest point near an edge with no reduction, or influence, on the anchor capacity is called the _________ ______ ________.

A

Critical Edge Distance

39
Q

The minimum spacing for each type of anchor is expressed in terms of _____.

A

Embedment Depth

40
Q

As the depth of embedment increases, a _____ cone of influence is created.

A

larger

41
Q

The reaction of metal with environmental elements, including rain, condensation, humidity, sprayed water, chemicals, gases, pollutants, and building materials. ________ reduces the strength of an anchor, and may occur locally (e.g., pitting) or uniformly over an entire surface.

A

Corrosion

42
Q

There are two types of adhesive anchor systems available

A

Capsule and Injection

43
Q

Because Hilti’s vinylester resin has a very low viscosity, it ____

A

penetrates better into the concrete pores, producing a keying effect along with adhesion

44
Q

The system in which the resin and hardener are self-contained in either glass or foil packaging is the _____.

A

Capsule System

45

HIT system, is designed for attaching medium to heavy-duty loads to concrete, brick, masonry, grout, and stone.

A

Hilti Injection Technique

47
