PLANETARY BOUNDARY LAYER MODELING AND STANDARD PROVISIONS FOR TALL BUILDING DESIGN

Abstract
According to recent results of Planetary Boundary Layer research relevant to tall building design, for elevations of up to at least 1 km: (i) the longitudinal mean wind speeds are monotonically increasing with height, and (ii) veering angles are negligible for practical structural engineering purposes. It is shown that, for these reasons, to avoid unconservative designs an explicit derogation from the ASCE 7 Standard specification of the gradient heights zg is necessary for buildings with heights greater than zg.
