Projects : Task Order 29

Development of Technical Brief on Structural Design Issues –
Seismic Design of Steel Special Concentrically Braced Frame Systems

SUMMARY

The primary objective of this task is to produce a new techbrief addressing Steel Special Concentrically Braced Frames (SCBF), including buckling restrained braced frames (BRBF). This techbrief will be a synthesis of model building code requirements and leading practitioner-recognized techniques, resulting in clear and concise analysis, design, and construction guidance for use by practicing structural engineers.

Work to be carried out under this task order includes: (1) project management and oversight, including the selection and confirmation of key project personnel; (2) preparation of a Project Work Plan; (3) update of a NIST project description; (4) preparation, review, and revision of an initial draft of the techbrief; (5) preparation of a final draft version of the techbrief for review; (6) preparation of a final camera-ready version of the techbrief for printing and dissemination; (7) preparation of a letter report outlining potential topics for future techbriefs related to steel design; and (8) presentation of in-person status reports at NIST offices in Gaithersburg, Maryland, and at NEHRP Consultants Joint Venture offices in Redwood City, California.
