Planetary Boundary Layer Modeling and Standard Provisions for Supertall Building Design
Publication: Journal of Structural Engineering
Volume 143, Issue 8
Abstract
According to recent results of planetary boundary layer research relevant to the design of tall buildings subjected to large-scale synoptic storm winds, for elevations of up to at least 1 km, the longitudinal mean wind speeds are monotonically increasing with height. It is shown that, for this reason, to avoid the possible unconservative design of supertall buildings significantly affected aerodynamically by neighboring buildings, an explicit derogation from the ASCE 7 standard specification of the gradient heights is necessary for buildings with heights greater than .
