Traditionally, wind loading prescribed for structural design has been based on ‘straight and steady’ wind flow that is generated in the wind tunnel and matches the properties of atmospheric boundary layer in some strong wind conditions. However, thunderstorms and tornadoes cause significant damage and produce wind speeds that ‘control’ wind design of structures in some U.S. locations. Wind and wind loading characteristics that are poorly characterized in the field and therefore difficult to replicate in the wind tunnel. The importance of these storm types are undeniable and researchers and practitioners are working towards incorporating them in some manner within wind load codes and standards. This presentation will discuss the latest efforts in both research and practice towards this end.
