These tests established that the zoning for the roof on these low-slope roof structures was heavily dependent on the building height, h, and much less dependent on the plan dimensions of the building. 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.
