Wind pressure measurement experiment with urban model built based on point cloud data for wind induced damage analysis

Abstract

Current state-of-the-art methodology for wind induced damage analysis employs, as wind hazard indicator, the wind speeds measured by nearby anemometers or the wind field obtained by reanalysis with a weather model. However, the physical parameter that directly affects wind damage is, except for flying debris induced damage, wind pressures acting on respective components of buildings. Thus, it is sound that wind pressure is employed as the wind hazard indicator in damage analyses. This study aims to develop a method to build wind pressure experiment models using point cloud data generated based on UAV aerial photos and a 3D printer, and then to investigate the validity of the estimated wind pressure coefficient obtained using such models.
