A Study on Development and Utilization of Wind Hazard Maps
Young-Kyu Lee, Sung-Su Lee, Hee-Jung Ham
Abstract
In this study, a wind hazard map over Korea peninsula based on geographical information is developed, which consists of the surface roughness model, the topographical effect model and the homogeneous wind model. The surface roughness model is assessed to evaluate the effect of the surface roughness on the wind field near ground. The topographical effect model is assessed to quantify the effect of the speed-up caused by topology, which is calculated by adopting the topographical effect factor in Korea building code (2005). The homogeneous wind map is created either by a frequency analysis method for meteorological data or a typhoon simulation. The results show that the wind hazard map can be applied to the determination of insurance premium as well as the assessment of loss and damage.
Key Words: surface roughness model; topographical effect model; homogeneous wind model; frequency analysis; typhoon simulation; wind assessment
요지
본 연구에서는 지리정보기반의 강풍위해지도를 개발하였으며, 이는 지표조도모형, 지형할증모형, 균일강풍지도로 구성된다. 지표조도모형은 지표조도가 지표풍에 미치는 영향을 반영하기 위해서 개발되었다. 지형에 의한 풍속할증을 반영하기 위하여 지형 할증모형을 개발하였다. 지형에 의한 풍속할증은 건축구조설계기준(2005)을 채용하여 산정하였다. 균일강풍지도는 기상자료를 이용한 빈도분석법과 태풍 시뮬레이션을 통하여 개발되었다. 본 연구에서 개발한 강풍위해성 평가방법을 통한 강풍위해지도가 강풍에 의한 손실, 피해 및 보험료율 산정에 적용될 수 있음을 보였다.
핵심용어: 지표조도모형; 지형할증모형; 균일강풍지도; 빈도분석법; 태풍 시뮬레이션; 강풍 평가
