abstract

  • Full-scale structural monitoring and wind tunnel studies were conducted on a single-storey wood light-frame residential building which was constructed in Fredericton, New Brunswick, Canada and equipped with weather, pressure and load monitoring instruments. The 1:200-scale model of this building was also tested at the Building Aerodynamic Laboratory of Concordia University and the structural response of the building was evaluated through 3D finite-element analysis. The wind tunnel simulation and testing procedure are presented in detail. Effects of adjacent buildings and other obstacles on external surface pressures were evaluated to match typical field situations. Moreover, wind tunnel and full-scale data analysis outcomes are discussed for both mean and peak response, and computed pressure and force coefficients are presented and compared. The agreement between the two sets of measurements is generally satisfactory. Through the wind pressure surface distribution and load transferring inside the structural system, the general behavior of the wooden superstructure subjected to wind loads is evaluated. In addition to the pressure taps located on the envelope of the full-scale building, there were 51 foundation-to-wall and wall-to-roof load cells that captured the actual flow of internal force flows with load paths by which wind load was transferred from roof and wall surfaces to the foundation.
