Study On Numerical Simulation Of Wind Loads Coefficient And Wind-Resistant Measures Design Of Rural Buildings

The southeast coastal regions of China are those areas that typhoon often visits. Previouswind disaster surveys indicate that most destroyed buildings in the disaster are low-rise buildings.If construction met gale season, the house still could not form the whole, every part could notcoordinate to resist wind load, lost in a big way. Therefore it is of great significance to investigatethe wind-load characteristics of low-rise buildings and compare the difference of wind-loaddistribution between constructing house and constructed house, it is also significant to find outthe corresponding wind-resistant ways.In order to reveal the difference of wind load distribution in constructing house andconstructed house, this article has used numerical simulation techniques to analyze wind loaddistribution between constructing house and constructed house. The obtained numericalresults are compared with wind tunnel result, and the validity and accuracy of the numericalsimulation are demonstrated.After numerical simulation between constructing house and constructed house with differentopening locations on wall (front wall openings,front wall and back wall openings),we obtainedthe wind load distributed rule,location of the negative wind pressure, and distributed scope ofnegative wind pressure coefficient.On the fundament of these and field investigations of the buildings damage in our province,this article analyze the main factors that affect the wind-resistance capability of low-risebuildings, and we propose structure measure against typhoon of low-rise buildings in the housedesign.
