TI 809-26
1 March 2000
The LRFD Specification, published in 1993, is based upon AWS D1.1-92, and takes exception to certain
provisions of that edition. It is anticipated that a new LRFD Specification, containing both SI and US
Customary Units within one document, will be published by AISC in early 2000.
c. Specification for Structural Steel Buildings - Allowable Stress Design and Plastic Design. The ASD
Specification contains provisions regarding welding design and application. Section J contains design
provisions, and Section M contains limited supplemental information regarding quality and inspection.
The ASD Specification, published in 1989, is based upon the use of AWS D1.1-88, and takes exception
to certain provisions of AWS D1.1. Publication of an updated or new ASD Specification is not being
planned by AISC.
d. Seismic Provisions for Structural Steel Buildings. This AISC document addresses the design and
construction of structural steel and composite steel / reinforced concrete building systems in seismic
regions. It is applicable for use in either LRFD or ASD. The provisions are for the members and
connections that comprise the Seismic Force Resisting System (SFRS) in buildings that are classified as
Seismic Design Category D or higher in FEMA 302, NEHRP Recommended Provisions for Seismic
Regulations for New Buildings and Other Structures. These structures include all buildings with an SDS >=
0.50g (SD1 >= 0.20g), and Seismic Use Group III when SDS >= 0.33g (SD1 >= 0.133g). See TI 809-04,
Chapter 4. The Seismic Provisions document cites AWS D1.1-96 as the reference welding standard. Part
I, Section 7.3 is applicable to welded joints, containing provisions regarding Welding Procedure
Specification approvals, filler metal toughness requirements, and special concerns for discontinuities in
SFRS members.
e. Code of Standard Practice. The AISC Code of Standard Practice defines practices adopted as
commonly accepted standards of the structural steel fabricating industry. In the absence of other contract
documents, the trade practices of the document govern the fabrication and erection of structural steel.
Within the document, Materials are discussed in Section 5, Fabrication in Section 6, Erection in Section
7, and Quality Control in Section 8.
f. Manual of Steel Construction, LRFD, Metric Conversion. The AISC Manual of Steel Construction
contains informational tables and design aids, as well as the AISC Specifications themselves. The
Manual contains welding design aids in Volume II - Connections. Chapter 8 includes prequalified joint
details, AWS welding symbols, tables for eccentrically loaded fillet welds, design examples, and general
information regarding welding. Design examples are contained within Chapter 9 for Simple Shear and
PR Moment Connections, Chapter 10 for Fully Restrained (FR) Moment Connections, and Chapter 11 for
Connections for Tension and Compression. One is cautioned that the welded prequalified joint tables are
based upon AWS D1.1-92, and have been substantially revised in subsequent editions of AWS D1.1.
g. Manual of Steel Construction, LRFD. The AISC Manual of Steel Construction contains
informational tables and design aids, as well as the AISC Specifications themselves. When using LRFD,
the Manual of Steel Construction, 2nd Edition, is applicable, and is in two volumes. The Manual contains
welding design aids in Volume II - Connections. Chapter 8 includes prequalified joint details, AWS
welding symbols, tables for eccentrically loaded fillet welds, design examples, and general information
regarding welding. Design examples are contained within Chapter 9 for Simple Shear and PR Moment
Connections, Chapter 10 for Fully Restrained (FR) Moment Connections, and Chapter 11 for
Connections for Tension and Compression. One is cautioned that the welded prequalified joint tables are
based upon AWS D1.1-92, and have been substantially revised in subsequent editions of AWS D1.1.
h. Manual of Steel Construction, ASD. The AISC Manual of Steel Construction contains informational
