Abstract

In this study, the flow patterns and fluctuating wind pressure characteristics around the roof of a spherical dome with a low rise–span ratio (f/D) were analyzed in detail. Significant differences were observed when compared to the results of previous studies on spherical dome roofs with relatively high f/D. The flow-pattern-based zone divisions and zone-specific pressure spectra models proposed in previous studies have limitations when applied to a spherical dome with an f/D ratio of 0.1, which is the subject of this study. Therefore, this study modified and proposed zone division and pressure spectra modeling methods based on the zone division and pressure spectra models of previous studies, and applied them to spherical dome roofs with a low rise–span ratio. Based on spectral statistics, the average error between the measured and simulated spectra was less than 4%, demonstrating high accuracy.
