NEHRP Recommended Seismic Provisions for New Buildings and Other Structures. 2009 Edition
The 2009 edition of the NEHRP Recommended Seismic Provisions is the seventh update since the first publication in 1985. This new edition adopts ASCE/SEI 7-05 by reference, which allows the Provisions to resume its role as the resource for introducing new knowledge, innovative concepts, and design methods to improve the national seismic standards and codes. The Provisions are presented in a new one-volume format with three parts. Part 1 adopts ASCE/SEI 7-05 by reference and presents consensus approved modifications to the reference standard. Part 2 provides a completely rewritten commentary that explains how to design using the reference standard. Part 3 comprises a series of resource papers that focus on emerging seismic design concepts and methods for exposure to and trial use by the design community and on issues that have proven historically difficult or complex to adequately codify. FEMA P-750 CD contains the Provisions, design maps, and other supporting materials.
