1.0 RECOGNITION
HILTI KB1 Expansion Anchors recognized in this report
have been evaluated for use as torque-controlled, mechanical
expansion anchors. The structural performance properties of
the HILTI KB1 Expansion Anchors comply with the intent of
the provisions of the following codes and regulations as
alternative solutions:
• National Building Code of Canada 2015 (NBC 2015)
• CSA A23.3-14, Design of Concrete Structures
2.0 LIMITATIONS
Use of the HILTI KB1 Expansion Anchors recognized in this
report is subject to the following limitations:
2.1 KB1 Expansion Anchors are limited to the sizes,
embedment depths, spacings, and other installation
requirements as provided in NBC 2015, CSA A23.3-14, and
this report.
2.2 The KB1 Expansion Anchor installation shall be in
conformance with the manufacturer’s published installation
instructions and this report. Where there is a conflict between
the requirements of this report and the instructions, the more
restrictive shall prevail.
2.3 KB1 Expansion Anchors shall be limited to use in cracked
and uncracked normal-density concrete and structural low-
density concrete with a specified compressive strength, f’
c
from 20 MPa to 58 MPa.
2.4 The maximum value of f’
c
used in the calculation
equations given in this report shall be 55 MPa.
2.5 Minimum spacings and edge distances for anchors and
minimum thicknesses of members shall comply with Tables
3, 4 and 5, and Figure 5.
2.6 In accordance with CSA A23.3-14 Clause D.1.4, the use
of KB1 Expansion Anchors to resist high cycle fatigue,
impact, or shock loads is beyond the scope of this report.
2.7 KB1 Expansion Anchors may be installed in a region of
the concrete member where cracking has occurred or where
analysis indicates cracking may occur (f
t
> f
r
) at service load
levels, subject to the provisions of this report.
2.8 KB1 Expansion Anchors may be used to resist short-term
wind or earthquake loads, subject to the provisions of this
report. Wind or earthquake loads shall be determined
according to NBC 2015 Subsections 4.1.7 or 4.1.8.
2.9 Subject to specific requirements in NBC 2015 and the
acceptance of the authority having jurisdiction KB1
Expansion Anchors may be used with fire-resistance-rated
assemblies or structural members where one or more of the
following limitations are satisfied:
• Anchors are used to resist wind or earthquake loads
only.
• Anchors that support a fire-resistance-rated
envelope or a fire-resistance-rated membrane are
protected by approved fire-resistance-rated
materials, or have been evaluated for resistance to
fire exposure in accordance with standards
referenced in the NBC.
• Anchors are used to support nonstructural elements.
2.10 Uses of anchors where conditions are corrosive to steel
are beyond the scope of this report.
2.11 Anchors are manufactured by Hilti AG under an
approved quality-control program with inspections by
IAPMO-UES.
3.0 PRODUCT USE
3.1 General: The KB1 Expansion Anchors are used to resist
static, wind and earthquake tension and shear loads in
cracked and uncracked normal-density concrete and
structural low-density concrete that has a specified
compressive strength, f’
c
, between 20 MPa and 58 MPa.
Cracked concrete shall be assumed except for anchors located
in a region of the concrete member where analysis indicates
no cracking (uncracked) at service load levels or restrained
shrinkage. Cracked concrete also shall be assumed for
anchors in structures designed to resist for earthquake loads.
Installation instructions and information are set forth in
Section 3.3, Tables 1 through 3, and Figures 2 and 3a of
this report.
