풍압실험과 풍하중 기준에 따른 피크내압계수의 비교

This study has compared the equivalent internal pressure coefficients, (GCpi)eq, with 6 wind load provisions and wind tunnel test data. The wind load provisions are the ASCE 7-10, NBCC 2010, AS/NZS 2011, EN 2005, AIJ 2004 and KBC 2009. Experiment data on low-rise building have been obtained at the University of Western Ontario (UWO) to contribute to the NIST aerodynamic database. For the experiment, a model with 1:12 of roof slope and 4.9 and 12.2m of eave height was used under open terrain conditions. (GCpi)eq was re-normalized based on the internal pressure coefficients (GCpi) of ASCE 7-10.
