ASCE 7 & SEI Standards

  • ASCE/SEI 7 Minimum Design Loads For Buildings and Other Structures

  • ASCE 7-16

    The 2016 edition of ASCE Minimum Design Loads and Associated Criteria for Buildings and Other Structures will be available in July 2017. Learn more about the new digital platform ASCE 7 Online, as well as the new ASCE 7 Hazard Tool, and sign up for release updates.

    ASCE 7-16 TECHNICAL CHANGES

    The 2016 edition of ASCE 7 Minimum Design Loads and Associated Criteria for Buildings and Other Structures provides the most up-to-date and coordinated loading standard for structural design. Along with improved coordination and routine updates, ASCE 7-16 includes many significant changes as follows:

    • New seismic maps that reflect the updated National Seismic Hazard Maps, including increased requirements for the region surrounding Las Vegas, Nevada, to address local concerns. The basis for the increase was developed and supported by the State of Nevada Geologist’s office.
    • New wind speed maps that result in reduced wind speeds for much of the country and clarify the special wind study zones, including new maps for Hawaii. Also new maps for Risk Category IV separate from Category III.
    • New regional snow data generated by state Structural Engineers Associations in Colorado, Oregon, New Hampshire, Washington and other mountainous states, that is now directly  referenced and eliminates many, older site-specific Case Study zones.
    • Updated rain duration provisions align design requirements with International Plumbing Code provisions for drainage.
    • New provisions for performance fire design in Appendix E.
    • Entirely new chapter with tsunami design provisions, which is important to west coast states, Alaska, and Hawaii.
    • Fully coordinated with material standards referenced within ASCE 7-16 including AISC, AISI, AWC, and TMS standards along with the correlating text. This coordination ensures that all of the referenced standards within ASCE 7-16 are the same as those referenced by the 2018 I-Codes.

    Cost Impact

    Consistent with revisions to all editions of the ASCE 7 standard, some of the revisions will cause increases and some will cause decreases in the cost of construction for an overall project. In fact, the variability of the impacts on construction resulting from different hazards may be compounding or may negate the effects. The cost impact for each significant change to ASCE 7-16 has been considered and is described below. While it is recognized that the summary of impacts from ASCE 7-16 to overall construction as compared to ASCE 7-10 is project specific, impacts to a specific building component or industries may be significant for any isolated change in the standard.
