1.0 LIMITATIONS

Use of the HILTI KB1 Expansion Anchors recognized in

this report is subject to the following limitations:

2.1 The anchors shall be installed in accordance with the

IBC or IRC, this report, and the manufacturer’s printed

installation instructions (MPII). Where conflicts occur, the

more restrictive governs.

2.2 The anchor sizes, dimensions, and minimum

embedment depths shall be as set forth in this report.

2.3 The anchors shall be installed in cracked and

uncracked normal-weight or lightweight concrete having a

specified compressive strength, f’

, between 2,500 psi (17.2

MPa) and 8,500 psi (58.6 MPa), and cracked and uncracked

normal-weight or sand-lightweight concrete over metal deck

having a minimum specified compressive strength, f’

, of

3,000 psi (20.7 MPa).

2.4 For calculation purposes, the compressive strength

value, f’

, shall not exceed 8,000 psi (55.2 MPa).

2.5 Strength design values shall be determined in

accordance with Section 3.2.1 of this report. Loads applied

to the anchors shall be adjusted in accordance with Section

1605.2 of the IBC for strength design.

2.6 Allowable stress design values shall be determined in

accordance with Section 3.2.2 of this report. Loads applied

to the anchors shall be adjusted in accordance with Section

1605.3 of the IBC.

2.7 Anchor spacing, edge distance and minimum concrete

thickness shall comply with Table 3 of this report.

2.8 Prior to installation, calculations and design details

that demonstrate compliance to this report shall be

submitted to the building official. The calculations and

design details shall be prepared by a registered design

professional where required by the laws and statutes of the

jurisdiction in which the construction is to occur.

2.9 Since suitable criteria for evaluating performance is

not available, the use of the subject anchors for fatigue or

shock loading conditions is beyond the scope of this report.

2.10 Use of zinc-plated carbon steel anchor is limited to

dry, interior locations.

2.11 Periodic special inspection shall be provided in

accordance with Section 3.4 of this report.

2.12 Where not otherwise prohibited in the applicable code,

anchors permitted for use with fire-resistant-rated

construction provided at least one of the following

conditions is satisfied:

● Anchors are used to resist wind or seismic forces

only.

● Anchors that support fire-resistance-rated

construction or gravity load-bearing structural

elements are within a fire-resistance-rated

envelope or a fire-resistance membrane, are

protected by approved fire-resistance-rated

materials, or have been evaluated for resistance to

fire exposure in accordance with recognized

standards.

● Anchors are used to support nonstructural

elements.
