The 2018 IBC and the referenced Standard are being adopted by a few jurisdictions and will become more widely used in 2019. In conjunction with the new roof pressure coefficients, it was determined that the existing roof zoning used in ASCE 7-10 and previous editions of the Standard did not fit well with the roof pressure distributions that were found during these new tests for low-slope ( 7 degrees) roof structures. This study focused on the non-hurricane areas of the country and used a new procedure that separated the available data by windstorm type and accounted for changes in the site exposure characteristics at the recording anemometers.
