Previous investigations verified that the relative height of low-rise flat-roof buildings have a notable effect on the wind load distribution.However

similar studies on the gable roofed building is so limited.In this study

the computational fluid dynamics method was used to simulate the wind load and wind-induced interference effects between two low-rise buildings and irregular low rise building group at different heights

based on the meteorological data of typhoon Meranti landed in a coastal area of southeast China in 2016.Results showed that the negative wind pressure coefficients of the leeward roof of the disturbed building decreases with increases in the height ratio when the height ratio is less than 2 between two low-rise gable roof buildings.The wind pressure coefficients of the leeward roof are negative and will increase with increasing height ratio when the height ratio is greater than 1.For the irregular low-rise building group

a wind angle of 60 degree is the most unfavorable wind direction.Overall

the negative wind pressure coefficients of the roof increase if the height increases and decrease with a constant height.
