WASHINGTON, D.C. – The
American Iron and Steel Institute (AISI) has updated 14 test standards in its
S900-series, providing a complete series of updated test methods that supersede
the previously published 2013 series. All test standards have been approved by
the American National Standards Institute (ANSI) and are available for downloading
free of charge at www.aisistandards.org.
“The AISI test standards are
updated every five years to facilitate research and development leading to
improved state-of-the-art solutions in steel for the construction market,” said
Jay Larson, P.E., F.ASCE, Managing Director, Construction Technical Program. “We
also updated the titles for the 2017 series, so they have a more consistent
format but differ slightly from the titles in the previous series. The suite of
test standards is often referenced in industry acceptance criteria, providing a
level playing field for establishing the performance characteristics of unique
products and applications.”
The updated test standards
include the following:
- AISI S901-17, Test Standard for Determining the Rotational-Lateral
Stiffness of Beam-to-Panel Assemblies (revision of AISI
S901-13) - This test standard is used primarily in determining the strength
of beams connected to panels as part of a structural assembly.
- AISI S902-17, Test Standard for Determining the Effective
Area of Cold-Formed Steel Compression Members (revision of AISI
- This test standard primarily considers the effects of local
buckling and residual stresses and is applied to solid or perforated
columns that have holes (or hole patterns) in the flat and/or curved
elements of the cross-section.
- AISI S903-17, Test Standard for
Determining the Uniform and Local Ductility of Carbon and Low-Alloy Steels (revision
of AISI S903-13)
- This test standard is primarily used as an alternative method of
determining if steel has adequate ductility as defined in AISI S100, North
American Specification for the Design of Cold-Formed Steel Structural
- AISI S904-17, Test Standard for
Determining the Tensile and Shear Strengths of Steel Screws (revision
of AISI S904-13) – This
test standard covers thread-forming or thread-cutting screws, with or
without a self-drilling point, and with or without washers that are used
to connect cold-formed sheet steel materials.
- AISI S905-17, Test Standard for Determining
the Strength and Deformation Characteristics of Cold-Formed Steel
Connections (revision of AISI S905-13) – This test standard includes
several performance test methods that cover the determination of the
strength and deformation of mechanically fastened or welded
connections for cold-formed steel building components, and are based
extensively on test methods used successfully in the past.
- AISI S906-17, Test Standard for Determining the Load-Carrying Strength of
Panels and Anchor-to-Panel Attachments for Roof or Siding Systems Tested
in Accordance With ASTM E1592 (revision of AISI S906-13) - This test standard extends and
provides the methodology for interpretation of test results
performed according to ASTM E1592.
- AISI S907-17, Test Standard for Determining
the Strength and Stiffness of Cold-Formed Steel Diaphragms by the
Cantilever Test Method (revision of AISI S907-13) - This test standard covers the
determination of the nominal diaphragm web shear strength and web shear
stiffness, or flexibility, where framed wall, roof or
floor cold-formed steel deck diaphragm construction is to be used.
- AISI S908-17, Test Standard for Determining the
Flexural Strength Reduction Factor of Purlins Supporting a Standing
Seam Roof System (revision of AISI S908-13) - This test standard is used
to obtain the reduction factor for determining
the nominal flexural strength of a purlin supporting a standing seam roof
- AISI S909-17, Test Standard for
Determining the Web Crippling Strength of Cold-Formed Steel Flexural
Members (revision of AISI S909-13) - This test standard establishes procedures for determining
the web crippling strength of cold-formed steel flexural members.
- AISI S910-17, Test Standard for Determining
the Distortional Buckling Strength of Cold-Formed Steel Hat-Shaped Compression
Members (revision of AISI S910-13) - This test standard establishes procedures for determining
the distortional buckling strength of cold-formed steel hat-shaped
compression members with an open cross-section.
- AISI S911-17, Test Standard for Determining
the Flexural Strength of Cold-Formed Steel Hat-Shaped Members (revision
of AISI S911-13) - This
test standard establishes procedures for determining the nominal flexural
strength of an open hat-shaped cross-section subject to negative bending
- AISI S912-17, Test Standard for
Determining the Strength of a Roof Panel-to-Purlin-to-Anchorage Device
Connection (revision of AISI S912-13) – This test standard is used
to obtain lower bound strength values for the roof
panel-to-purlin-to-anchorage device connections in through-fastened and
standing seam, multi-span, multi-purlin line roof systems. The test is not
intended to determine the ultimate strength of the connections.
- AISI S913-17, Test Standard for Determining
the Strength and Deformation Behavior of Hold-Downs Attached to
Cold-Formed Steel Structural Framing (revision of AISI S913-13) - This test standard provides two
methods to determine both the strength and deformation of hold-downs used
in light-frame construction. One of the test methods determines the
strength and deformation of the hold-down device, and the other test
method determines the strength and deformation of the hold-down assembly.
- AISI S914-17, Test Standard for Determining
the Strength and Deformation Behavior of Joist Connectors Attached to
Cold-Formed Steel Structural Framing (revision of AISI S914-13) - This test standard
provides a method to determine both the strength and deformation of joist
hangers and similar devices used in light-frame construction.
