EVALUATION OF PEAK PRESSURE COEFFICIENTS ON LOW-RISE BUILDING BASED ON PROBABILISTIC THEORY

In current AIJ-RLB (2015), the peak pressure coefficients were prescribed by an ensemble average of ten or twenty 10-minute samples obtained from the wind tunnel tests. In this study, 12,780 10-munute samples of the peak pressure coefficients were measured, and the cumulative distributions were identified using the extreme value distributions and the effect of number of 10-minute samples were examined. Lastly, design values were proposed based the zones of low-rise building. Using the proposed values, the peak pressure coefficients corresponding to the specific non-exceedance probabilities of the wind loads can be calculated from the ensemble averaged peak pressure coefficients. © 2023 Architectural Institute of Japan.
