International Building Code 1714.1

General. In evaluating the physical properties of materials
and methods of construction that are not capable of being
designed by approved engineering analysis or do not comply
with applicable material design standards listed in Chapter 35,
the structural adequacy shall be predetermined based on the
load test criteria established in this section.

International Building Code 1714.2

Load test procedures specified. Where specific load
test procedures, load factors and acceptance criteria are
included in the applicable design standards listed in Chapter
35, such test procedures, load factors and acceptance criteria
shall apply. In the absence of specific test procedures, load factors
or acceptance criteria, the corresponding provisions in
Section 1714.3 shall apply.

International Building Code 1714.3

Load test procedures not specified. Where load test
procedures are not specified in the applicable design standards
listed in Chapter 35, the load-bearing and deformation capacity
of structural components and assemblies shall be determined
on the basis of a test procedure developed by a registered
design professional that simulates applicable loading and
deformation conditions. For components and assemblies that
are not a part of the seismic-load-resisting system, the test shall
be as specified in Section 1714.3.1. Load tests shall simulate
the applicable loading conditions specified in Chapter 16.

Test procedure. The test assembly shall be subjected
to an increasing superimposed load equal to not less
than two times the superimposed design load. The test load
shall be left in place for a period of 24 hours. The tested
assembly shall be considered to have successfully met the
test requirements if the assembly recovers not less than 75
percent of the maximum deflection within 24 hours after the
removal of the test load. The test assembly shall then be
reloaded and subjected to an increasing superimposed load
until either structural failure occurs or the superimposed
load is equal to two and one-half times the load at which the
deflection limitations specified in Section 1714.3.2 were
reached, or the load is equal to two and one-half times the
superimposed design load. In the case of structural components
and assemblies for which deflection limitations are
not specified in Section 1714.3.2, the test specimen shall be
subjected to an increasing superimposed load until structural
failure occurs or the load is equal to two and one-half
times the desired superimposed design load. The allowable
superimposed design load shall be taken as the lesser of:
1. The load at the deflection limitation given in Section
1714.3.2.
2. The failure load divided by 2.5.
3. The maximum load applied divided by 2.5.

Deflection. The deflection of structural members
under the design load shall not exceed the limitations in Section
1604.3.

International Building Code 1714.3.2

Deflection. The deflection of structural members
under the design load shall not exceed the limitations in Section
1604.3.

International Building Code 1714.4

Wall and partition assemblies. Load-bearingwall and
partition assemblies shall sustain the test load both with and
without window framing. The test load shall include all design
load components.Wall and partition assemblies shall be tested
both with and without door and window framing.

International Building Code 1714.5

Exterior window and door assemblies. The design
pressure rating of exterior windows and doors in buildings
shall be determined in accordance with Section 1714.5.1 or
1714.5.2.
Exception: Structural wind load design pressures for window
units smaller than the size tested in accordance with
Section 1714.5.1 or 1714.5.2 shall be permitted to be higher
than the design value of the tested unit provided such higher
pressures are determined by accepted engineering analysis.
All components of the small unit shall be the same as the
2006 INTERNATIONAL BUILDING CODE 341
STRUCTURAL TESTS AND SPECIAL INSPECTIONS
tested unit. Where such calculated design pressures are
used, they shall be validated by an additional test of the window
unit having the highest allowable design pressure.

Exterior windows and doors. Exterior windows
and sliding doors shall be tested and labeled as conforming
to AAMA/WDMA/CSA101/I.S.2/A440. The label shall
state the name of the manufacturer, the approved labeling
agency and the product designation as specified in AAMA/
WDMA/CSA101/I.S.2/A440. Exterior side-hinged doors
shall be tested and labeled as conforming to
AAMA/WDMA/CSA101/I.S.2/A440 or comply with Section
1714.5.2. Products tested and labeled as conforming to
AAMA/WDMA/CSA 101/I.S.2/A440 shall not be subject
to the requirements of Sections 2403.2 and 2403.3.

Exterior windows and door assemblies not provided
for in Section 1714.5.1. Exterior window and door
assemblies shall be tested in accordance with ASTM E 330.
Exterior windowand door assemblies containing glass shall
comply with Section 2403. The design pressure for testing
shall be calculated in accordance with Chapter 16. Each
assembly shall be tested for 10 seconds at a load equal to 1.5
times the design pressure.

Test specimens. Test specimens and construction shall
be representative of the materials, workmanship and details
normally used in practice. The properties of the materials used
to construct the test assembly shall be determined on the basis
of tests on samples taken from the load assembly or on representative
samples of the materials used to construct the load test
assembly. Required tests shall be conducted or witnessed by an
approved agency.
