      ASCE Structural Engineering Institute Announces New Prestandard for Performance-Based Wind Design

      August 23, 2019

      RESTON, Va.  - The American Society of Civil Engineers (ASCE) Structural Engineering Institute (SEI) has published ASCE/SEI Prestandard for Performance-Based Wind Design . SEI received a research grant from the Charles Pankow Foundation  for $150,000 with co-funding support from the ACI Foundation, American Institute of Steel Construction, ASCE Industry Leaders Council and the MKA Foundation, to develop and publish the Prestandard .

      This Prestandard  presents a recommended alternative to the prescriptive procedures for wind design of buildings contained in the International Building Code  (IBC) and in the nationally adopted standard, Minimum Design Loads and Associated Criteria for Buildings and Other Structures  (ASCE 7).

      While providing performance-based approach for wind that is compatible with current performance-based approaches for seismic design, if properly implemented, the Prestandard  results in buildings that are capable of achieving the wind performance objectives specified by ASCE 7-and in many instances-superior performance to these objectives.

      "We are thankful for the Charles Pankow Foundation and industry partners' funding of the development of the ASCE/SEI Pre-Standard for Performance-Based Design for Wind," said Don Scott, P.E., Vice President and Director of Engineering of PCS Structural Solutions and Prime Investigator who led the Prestandard  development team. "This research will advance the use of performance-based design procedures for the design of tall buildings and enhance their performance during wind events. These procedures will allow for innovation by the design profession to use unique or unusual structural systems, incorporate novel materials and design approaches for tall buildings to better protect the health, safety and welfare of the public."

      The Prestandard's  intended audience includes structural engineers, architects, building component and cladding specifiers/designers and building officials engaged in the wind design and review of buildings. Major innovations introduced in the Prestandard  include nonlinear dynamic analysis for wind design, limited inelasticity in the Main Wind Force Resisting System elements, system-based performance criteria and enhanced design criteria for the building envelope.  

      ASCE/SEI Prestandard for Performance-Based Wind Design   is available as a free download from ASCE , SEI  and CPF  websites.
