INFLUENCES OF PILOTI-TYPE BUILDING ON THE SURROUNDING WIND ENVIRONMENT AND WIND PRESSURE ON A DOWNWIND BUILDING

Abstract

Climate change has led to an increase in floods caused by heavy rain. One of the measures to reduce damages due to the flood is the use of piloti-type buildings. In this study, LES was conducted to analyze the influences of a piloti-type building on the surrounding wind environment and the wind pressure on the building located on the leeward side of the pilotitype building. It was found that good ventilation was obtained in the piloti space, but at the same time, some local high wind speed areas occurred. It was also found that large positive peak wind pressure coefficients appeared on a windward side wall of the building located on the leeward side of the piloti-type building.
