Parametric Calibration of BS 6399: 2: 1997 (Effective Dynamic Pressures)

This paper compares the effective dynamic pressures from BS 6399 Loading for Buildings: Part 2: Code of practice for wind loads: 1997 (BS 6399: 2) Bristol against the previous practice defined by CP3: V: 2: 1972 (CP 3). The calibration was performed for 485 sites around the coastline and over 2500 sites inland. In order to represent current practice fairly, it uses the most common (mis)interpretations of CP 3. The results show that using the simplest, most conservative options, BS 6399: 2 gives 5% lower Values on average and 12% higher values as the typical worst case, while using the optimum options, BS 6399: 2 gives 16% lower values on average and 1% higher values as the typical worst case.
