abstract

  • Full-scale studies, wind tunnel experiments and finite element modeling were used for the study of a wooden low-rise building subjected to wind loads. The conclusions of this study can be summarized as follows: 1) The pressure distribution comparison between the wind tunnel and the full-scale results shows good agreement. Some discrepancies can be justified by the high fluctuations of the wind direction in the full-scale records. The peak pressure coefficient comparison is characterized by higher discrepancies. 2) The wind tunnel / full-scale general agreement allows the use of wind tunnel data for numerical simulation. 3) The comparison between the full-scale load cell readings and the base reactions computed by the finite element analysis made in the form of force coefficients shows good agreement, as far as mean values are concerned. Higher values of forces have been found by using the measured pressure coefficients on the building envelope in comparison with those recorded directly by load cells placed on building foundation. 4) The experimental critical local pressures (suctions) tend to be higher (lower) in comparison to the code suggested values. Topography and surrounding structures effects can justify these discrepancies. 5) Field pressure data are, in some cases, significantly higher than the corresponding ASCE 7 values for components and cladding. The study confirms that full-scale structural monitoring is very difficult, time-consuming, yet necessary task. The ongoing collection of data will lead to more complete outcomes. Furthermore, roof load cells have been installed on the base of roof trusses and a more detailed picture of the structural response will be available in the near future. © 2008 ASCE.
