Description
This paper describes some problems for the evaluation method of peak wind pressure coefficients on a flat roof. The pressure distribution on a roof is different from that on a wall, although the same factors of the decay factor and the representative area are usually used to evaluate the appropriate pressure coefficients. This tributary area for evaluation the coefficients of a roof are smaller than that area of wall. Furthermore, the peak value evaluated from the moving average method was often smaller than the value from the spacing average method. Therefore, the averaging time for general part rather than the corner part is decided by using the decay factor k of 4.5. The suitable averaging time for the corner part should be selected significantly lager than the averaging time for general part.
