1.1?This specification covers steel stud assemblies for shear reinforcement of concrete. Stud assemblies consist of either single-headed studs (Type 1) attached to a structural steel base rail by structural welding or stud welding, or double-headed studs (Type 2) mechanically crimped into a non-structural steel shape or attached to a steel plate by spot welding or tack welding. These stud assemblies are not intended for use as shear connectors in steel-concrete composite construction. Note 1:?The configuration of the studs for stud assemblies is
much different than the configuration of the headed-type studs
prescribed in Clause 9, Figure 9.1 of AWS D1.1/D1.1M. Ratios of the
cross-sectional areas of the head-to-shank of the AWS D1.1/D1.1M
studs range from about 2.5 to 4. In contrast, this specification
requires the area of the head of the studs for stud assemblies to
be at least 10 times the area of the shank. Thus, the standard
headed-type studs in Clause 9, Figure 9.1 of AWS D1.1/D1.1M do not
conform to the requirements of this specification for use as stud
assemblies for shear reinforcement.
1.2?This specification is applicable for orders in either inch-pound units or in SI units. 1.3?The values stated either in inch-pound or SI units are to be regarded as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with this specification. 1.4?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
