초록
이 연구에서는 KBC 2016 풍하중의 산정 배경을 구체적으로 설명하고, 콘크리트 이중골조 고층건물에서의 풍하중과 지진하중을 비교하였다. 풍하중은 평균성분, 비공진성분, 공진성분으로 구성되며, 건물이 고층화될수록 공진성분이 우세해진다. 구조물의 형상비가 3보다 큰 경우 풍직각방향 및 비틀림 하중을 고려하며, 풍방향하중과 설계지진하중보다 풍직각방향 풍하중이 지배적이게 된다.
Abstract
In this study, a detailed background of wind load determination according to KBC 2016 and its application to high-rise concrete buildings with dual system are presented. The wind load consists of mean, background, and resonant components. As a building becomes higher, the resonant component dominates the wind load. When the aspect ratio exceeds 3, across-wind and torsional wind loads are considered. The across-wind loads to buildings with aspect ratio exceeding 3 become larger than along-wind loads and seismic loads.
