Interpolation Issues In the Estimation of Peak Internal Forces Using Wind Pressure Databases



Joseph A. Main


A procedure is presented that makes use of measured pressures to predict peak static responses of low buildings, for cases in which no wind tunnel model is available with dimensions matching those of the structure of interest. The proposed approach interpolates peak structural responses rather than wind pressures, thus eliminating the need to account explicitly for spatial and temporal distributions in the interpolation scheme. The procedure makes use of pressures measured on models with differing dimensions by scaling the pressure tap coordinates to match the dimensions of the structure of interest. A fairly simple multi-dimensional interpolation scheme is presented to estimate peak responses for the structure of interest from peak responses computed using pressure measurements from a number of different building models An example illustrating the procedure is presented.
