The biggest impact on the cladding design of buildings is wind loads. Wind tunnel tests were conducted to examine the applicability of current wind load standards about membrane retractable roof spatial structure. A dome model with a circular shape that is retractable to the center of the dome was made (Opening ratio = 0, 10, 30, 50). In addition, height adjustable turntables were made and tested with five patterns with H/D = 0.1, 0.2, 0.3, 0.4 and 0.5. The maximum wind pressure coefficient and the minimum wind pressure coefficient for the cladding were analyzed and the experimental wind pressure coefficient were compared with the current wind load standards, KBC2016 and AIJ-RLB(2015). The experimental value and the reference value of the enclosed roof were very similar and showed possibility of application, but opened roof case was found that the reference value was underestimated.

중정형 건축물의 중정측 외장재 설계를 위한 외압계수분포 특징을 알아보기 위해 풍압실험을 실시하였다. 본 연구를 위하여 형상비와 중정의 폭을 변화시킨 4개의 모형을 제작하였으며, 풍동실험은 금오공과대학교 토출식 경계층풍동에서 실시하였다. 본 연구의 결과로부터 중정측의 외압계수는 건물외측의 외압계수보다 감소하는 것으로 나타났다.
