Recent and Current Wind Engineering Research at the National Institute of Standards and Technology

摘要

This paper briefly reviews recent and current National Institute of Standards and Technology (NIST) research aimed at improving standard provisions and advancing structural design practice for wind loads. The research covers: (ⅰ) New wind speed maps for the conterminous United States; (ⅱ) Risk-consistent estimation of wind load factors for use with the wind tunnel procedure; (ⅲ) Modern peaks-over-threshold approaches to estimation of peak wind effects; (ⅳ) User-friendly procedures for the database-assisted design of rigid and flexible structures; (ⅴ) Novel approaches to codification of pressures on cladding and components; (ⅵ) Modern modeling of synoptic storm planetary boundary layers and its implications for super-tall building design; (ⅶ) Computational Wind Engineering (CWE); (ⅷ) Tornado climatology and development of tornado-resistant design methodologies; (ix) Joint climatology of wind speeds, storm surge and waves heights, and estimates of their combined effects on structures.
