Abstract:

This paper has reviewed current methods of determining spatially-averaged time-varying wind loads on wind tunnel building models. Some of the possibilities opened by simultaneous multi-channel sampling have been illustrated, using both on-line and off-line computation. In particular, the technique of acquiring time histories for post-analysis has been identified as one which is particularly useful and flexible, and one which may become increasingly popular as computing power and storage capabilities continue to increase. The technique's application to non-linear response problems is already well established.
