It is often important for the structural engineer and the building services consultant to know the wind pressures acting on the façades and roofs of a building. The structural engineer is interested in the wind forces on the building, while the technical consultant focuses on the overpressure and underpressure at the locations of air intake and exhaust grilles for mechanical ventilation.
Insight into these pressures can be obtained by placing pressure taps in a scale model and conducting measurements in the wind tunnel. These measurements are carried out and processed according to the guidelines provided in CUR Recommendation C103, using an extreme value analysis to determine the critical pressures on the façade.
To determine the total forces and moments on the building, measurements can also be taken using a balance. Peutz has a dynamic piezoelectric six-component balance available for this purpose.
