The 2015 NEHRP Provisions marks the ninth edition of this technical resource document since its first publication in 1985. FEMA is proud to sponsor this cycle of the NEHRP Provisions update, and to publish the new edition for use by national codes and standards organizations and the general public. The 2015 NEHRP Provisions are a new knowledge-based resource document intended to translate research results into engineering design practice. The new changes in the 2015 NEHRP Provisions have incorporated extensive results and findings from recent research projects, problem-focused studies, and post-earthquake investigation reports conducted by various professional organizations, research institutes, universities, material industries, and the NEHRP agencies. Similar to the previous edition, the 2015 NEHRP Provisions have adopted by reference the American Structural Engineers Association (ASCE) / Structural Engineering Institute (SEI) standard ASCE/SEI 7-10: Minimum Design Loads for New Buildings and Other Structures as the baseline.
