TI 809-26
1 March 2000
Instructions necessary to provide serviceable buildings and to assure load path integrity and continuity is
included. Requirements unique to Army, Navy, and Air Force facilities are indicated. Supplemental
information to help engineers interpret and apply code provisions, and meet serviceability and strength
performance objectives is also included in the TI.
c. TI 809-04 Seismic Design for Buildings. This document provides qualified designers with the
criteria and guidance for the performance-based seismic analysis and design of new military buildings,
and the non-structural systems and components in those buildings. Chapter 7 includes discussion of
structural steel framing systems, but does not provide specific details for welded connections in those
systems.
d. TI 809-05 Seismic Evaluation and Rehabilitation for Buildings. This document is intended to
provide qualified designers with the necessary criteria and guidance for the performance-based seismic
analysis and design of new military buildings, and the nonstructural systems and components in the
buildings. The primary basis for this document is the 1997 edition of the NEHRP Provisions for Seismic
Regulations for New Buildings and Other Structures (FEMA 302). This document provides guidance in
the interpretation and implementation of the FEMA 302 provisions for the Life Safety performance
objective for all buildings, and it provides criteria for the design and analysis of buildings with enhanced
performance objectives.
e. TI 809-07 Design of Cold-Formed Load Bearing Steel Systems and Masonry Veneer / Steel Stud
Walls. This document provides design guidance on the use of cold-formed steel systems for both load-
bearing and nonload-bearing applications. Cold-formed steel members are generally of a thickness that
welding is governed by AWS D1.3 Structural Welding Code - Sheet Steel, rather than AWS D1.1
Structural Welding Code - Steel, and therefore are not covered by TI 809-26.
f. TI 809-30 Metal Building Systems. This document provides guidance on the use of Metal Building
Systems, defined as a complete integrated set of mutually dependent components and assemblies that
form a building, including primary and secondary framing, covering and accessories. These types of
structures were previously referred to as pre-engineered buildings. Paragraph 5.i addresses welding for
manufacturers not AISC certified in Category MB.
g. TM 5-809-6 Structural Design Criteria for Structures Other Than Buildings. This document will
become TI 809-03. Revise as needed.
3. AISC SPECIFICATIONS AND STANDARDS.
a. Metric Load and Resistance Design Specification for Structural Steel Buildings. The Metric LRFD
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 Metric LRFD Specification, published in 1994, is based upon AWS D1.1-92, and takes exception to
certain provisions of that edition. This metric specification is a dimensional conversion of the December
1, 1993 customary units edition. The principles and concepts of these two specifications (metric and
customary) are identical, only the units differ. 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.
b. Load and Resistance Factor Design Specification for Structural Steel Buildings. The LRFD
Specification contains provisions regarding welding design and application. Section J contains design
provisions, and Section M contains limited supplemental information regarding quality and inspection.
