Abstract

The effect of gas resonance on wind tunnel experiment for internal pressure in a building, especially in a two-compartment or multi-compartment building, with a dominant opening cannot be omitted. Similarity and additional internal volume requirements for internal pressure experiment are firstly described. The building internal cavity volume used at model-scale should be distorted by a factor equaling the square of the ratio of the full-scale to model-scale velocities, and the additional internal volume must be a deep and narrow cavity. Then, the gas natural frequency equation is introduced from reciprocating compressor piping system into wind tunnel studies on internal pressure. Finally, wind tunnel experiments on internal pressure for a two-compartment building with two kinds of additional distorted volumes are carried out. Results show that the measured internal pressure response will be inaccurate because of the influence of gas resonance when the additional distorted volumes are much deeper and narrower.

Key words

building with opening / wind-induced internal pressure / gas resonance / wind tunnel experiment / similarity law.
