Abstract
Compatible with the proposed British Standard BS 6399: Part 2. Deals with the assessment of wind speeds over topographic features such as hills, ridges, escarpments and cliffs for wind loading calculations. The information here is generally similar to that in Digest 283, but now the new topography factor Stop is added to the wind speed for flat terrain. The proposals for the topography factor are soundly based on theory and agree in value to better than 10% for typical UK topography with the more empirical rules incorporated in BS 8100: Part 1: Lattice towers and masts.
