4) What is the value of large-scale testing to develop and validate computer simulations, as a vehicle for public education, to validate current building code prescriptive standards, and to aid in the design of credible standardized small-scale or single component tests?

Given the relative costs of the various data collection methods and the relative value of the data each produces, which methods represent the most cost effective ways of improving the scientific understanding of the effects of extreme winds on nonengineered structures? Which industries would be the most likely to use a facility capable of testing fullscale structures in a controlled environment and to what extent are they likely to use it?

Several of them indicated that interdisciplinary, coordinated research will be necessary to mitigate wind-related Tosses and that no facility should be established except as part of a well conceived national program. The respondents highlighted many benefits of a facility capable of testing large-scale structures in a simulated extreme wind environment, but they expressed concerns about the capability of such a facility to simulate the characteristics of the natural wind, as well as the potential costs, both startup and maintenance costs, of such a facility.

37 In general, the respondents indicated that there is a need for large-scare experimental data to help the public understand the relationship between wind speeds and wind damage. The misrepresentation of wind speeds in past extreme wind events may have misled the public about ^1_ _ ~ I ~ ___ 1 _ T 1 1 -, one Destructive power or extreme winces.

The proposed facility would enable studies of progressive damage to failure so that the wind speeds associated with the onset of specific damage could be determined. A full-scale testing facility could be good publicity and increase public awareness of the dangers posed by winds, provided the characteristics of extreme winds were adequately simulated and the costs of the facility were not so extreme that it would negatively affect public opinion about artificial destructive testing.
