Abstract
The paper deals with the exploration, by model tests, of the effects of roof parapets and roof projections onto the wind loading and of wall mullions (or ribs) onto the wall wind loading of bluff building forms. Results are presented that suggest that parapets are effective in equalizing the pressure distribution over the roof surface while slightly reducing the uplift source. Roof projections, on the other hand, have the opposite effects. The presence of wall mullions causes sawtooth-like deviations from the peripheral wall pressure distributuion for the no-rib case. The deviations are particularly significant in regions of attached flow and tend to become more pronounced with an increase in rib spacing.
