External Pressure Coefficients on Saw-Tooth and Mono-Sloped Roofs
A wind tunnel study to investigate wind pressures on single and multi-span saw-tooth roofs for a 1:100 geometrical scale model of a low-rise building was carried out in atmospheric boundary layer wind tunnel at the Wind Load Test Facility at Clemson University. The purpose of this investigation was to further investigate wind loads on low rise buildings with mono-sloped and saw-tooth roofs and study the validity of ASCE 7-02 specification on these buildings. By using larger models and a higher density of pressure tap than in previous studies, a greater resolution of the pressure variations was achieved. The paper presents representative results of the study that includes point and area-averaged wind pressure coefficients on models with varying spans and building heights. Local peak pressures and area-averaged pressures obtained in this study are compared with the design values specified in ASCE 7-02 and with results of previous wind tunnel studies. The results presented showed no significant difference in wind pressures between the windward span of the saw-tooth roof and the mono-sloped roof. Comparing results with ASCE 7-02 suggest that the current wind design provisions for mono-sloped roofs may be un-conservative.
