APPARATUS AND METHOD FOR CALCULATING DESIGN WIND SPEED USING REGRESSION ANALYSIS

摘要

The present invention relates to an apparatus and a method for calculating design wind speed using regression analysis. The apparatus for calculating the design wind speed according to an embodiment of the present invention comprises: an acquiring part for acquiring position data and altitude data on multiple points within a target area and overall height data in which the height of a building is reflected on the altitude; a regression equation calculation part for calculating a regression equation by using the regression analysis based on the position data and the altitude data; a ground surface height calculation part for calculating the height of a ground surface on each point by substituting the position data into the regression equation; a frequency distribution calculation part for calculating frequency distribution on a difference between the overall height calculated for each point and the height of the ground surface; a parameter value calculation part for allocating ground roughness to a grade of the frequency distribution, applying a weighting factor based on the frequency distribution to a parameter value set for each ground roughness and calculating a parameter value of the target area; and a wind speed calculation part for calculating the design wind speed on the target area by using the calculated parameter value.
