Wind-induced internal pressure load of buildings. Belastung von gebauden durch den windinduzierten innendruck.

The mean and dynamic internal and external pressures of an existing building (tennis hall) and a model of the building were measured and compared. Asystematic examination was made of the effects on wind-induced internal pressure in simple geometric models of flow profile, wind direction, building dimensions, openings and leakiness. Suggestions are proposed for changes to DIN 1055 Part 4. The Canadian, American, British and Swiss Standards on wind loads are compared.
