abstract

  • A low-rise test house built in Fredericton, New Brunswick was instrumented with weather, pressure and force monitoring equipment. Recently acquired field data were analyzed and used to validate simulation findings. In addition, simplified numerical results are compared to fullscale data to evaluate the structural attenuation of the test house. Forty pressure taps on the test house surface, along with six roof load cells installed in the wall-to-roof interface and twentyseven load cells at foundation provide a detailed picture of the house response. Results agree with previous findings regarding peak wind pressure estimation through wind tunnel tests. Discrepancies are more pronounced for corner and close to edge regions. Applied surface pressure and internal forces at key monitoring points are found to be less correlated for certain frames and wind directions. Attenuation introduced by the building system depends on the dynamic nature of wind loading and the connections of building structural and non-structural elements; it determines wind load paths in the structure, i.e. how the load is transferred from the envelope to the foundation.
