The local peak wind pressure coefficients for claddings should be determined in consideration of influence of the size or the shape well the position. Recommendations for Loads on Buildings (1993) by Architectural Institute of Japan shows that an average time of 0.5~1sec corresponds to the size of claddings of 1~10m. However, their relationship has not been well studied to date. Therefore, the purpose of the present study is to clarify the relationship between the average time and the area or shape of cladding which wind pressure is acting. The results of LES have led to understanding of the relationship of time-space evaluation of the peak wind pressure coefficients.
