Abstract

This study presents an analysis and characterization of dynamic tornado-induced pressures and internal forces of a low-rise building frame model using measurement data obtained from a tornado simulator. The time-varying mean and covariance of pressure are evaluated based on wavelet transform. The building frame responses are calculated from the statistics of pressures, and the equivalent static wind loads (ESWLs) causing peak responses are defined. The effect of translation speed of tornado vortex on frame responses is also explored. Finally, the tornado-induced responses are compared with those from ASCE 7-10.
