All Technical Briefs are also available for download in electronic format at the NEHRP web site: www.nehrp.gov/library/techbriefs.htm
In the future, NIST intends to produce one to three Technical Briefs per year that address topics of interest to earthquake professionals, primarily those in the design and construction industries. The Technical Brief concept was originally proposed by a group of nationally recognized earthquake professionals in 2003 in ATC-57, The Missing Piece: Improving Seismic Design and Construction Practices. NIST anticipates producing one on seismic design of reinforced concrete diaphragm analysis and design and another on guidelines for performing nonlinear structural analysis in 2010.
