| 요약1 |
이 연구에서는 지붕에 큰 개구부를 가진 개방형 돔 구조의 내부 지붕 표면에 작용하는 내부 압력에 대한 내부 체적의 영향을 조사하였다. Vs 조건(실제 규모의 구조물)에서 헬름홀츠 공명은 와류방출과 상호작용하여 약 67.5 Hz의 에너지를 증가되는 것을 확인하였다. 또한, 왜도와 첨도 분석을 통해 Vs 조건에서 풍압의 비가우시안 특성이 가장 뚜렷하게 나타나는 것을 확인하였다. |
| 요약2 |
This study examines how internal volume affects the internal pressure on the interior roof surface of an open dome structure with a central
opening. Wind tunnel tests were conducted using four different volume conditions, and internal pressure characteristics were analyzed through
mean values, standard deviation, power spectral density, skewness, and kurtosis. The findings indicate that internal volume impacts both the
magnitude and variability of internal pressure. In the Vs condition, Helmholtz resonance interacted with vortex shedding, amplifying energy
around 67.5 Hz. Although Helmholtz resonance appeared at higher frequencies with lower energy, its independent effect was limited. These
higher resonance frequencies, accompanied by relatively low energy levels, are notably different from those observed in previous studies that
focused on structures with smaller openings. Analysis of skewness and kurtosis confirmed that non-Gaussian behavior was most evident under
the Vs condition. |
