IAWE aylesbury collaborative experiment (ACE)

396 IAWE AYLESBURY COLLABORATIVE EXPERIMENT (ACE) AIMS The experiment seeks to improve the assessment of wind-induced loads on low-rise buildings through model-scale tests by resolving any differences between the various experimental techniques in current use and to assess the uncertainties inherent in measurement and modelling. The use of the BRE Aylesbury Experimental Building as the prototype enables this experiment to be calibrated against full-scale dat~ The experiment will also serve to define a set of standard model data, at various levels of sophistication or complexity, which newcomers to the field of Wind Engineering may use as benchmarks for the development of their simulation and analysis capability. ORGANISATION Collator and European Coordinator Dr. N.J. Cook, Building Research Station, Garston, Watford, WD2 7JR, United Kingdom. Coordinator for North and South America Dr. A.G. Davenport, Boundary Layer Wind Tunnel Laboratory, University of Western Ontario, London, Ontario, N6A 5B9, Canada. Coordinator for Australasia and Far East Dr. J.D. Holmes, Division of Building Research, C.S.I.R.O., Melbourne, Australia (after Jan. 1982}. MODEL BUILDING AND SITE The building to be modelled is the variable roof-pitch Aylesbury experimental building used by the U.K. Building Research Establishment between March 1972 and February 1974 for a series of full-scale tests. Participants will be issued with scale drawings and photographs of the building and its site. Three 1/100 scale models of the building will be circulated for testing, one by each of the coordinators. Each model will consist of a wall unit and four interchangeable roof units, pitches 5, 10, 15 and 22.5 degrees, and will be provided with pressure tappings at locations corresponding to the transducers of the prototype building. Participants are required to make their own models of the surrounding site. Participants are free to make their own models of the building, to any scale they wish, provided that the locations of the tapp'mgs correspond exactly with those of the circulating models and the prototype. Participants may also take measurements at other locations on their own models for their own benefit, but these measurements may not be suitable for the final collation of results. Any laboratory which wishes to participate should contact their respective Coordinator (unless they have already done so), giving the name and address of the principal researcher.
