the Metal Building Manufacturers Association and tested at Omega Point Laboratories to evaluate the fire performance of the junction between a one-hour fire rated wall assembly and the non-combustible metal roof panels (Ref Omega Point Project No 16343-108145) The fire exposure used to evaluate the joint was the time-temperature curve in ASTM E 119 for fire rated walls There is no test method for evaluating the fire integrity of the joint where a fire rated wall meets the roof insulation under noncombustible metal roof panels Also, building codes not require this joint to be fire rated This investigation serves to answer questions raised by building and fire code officials concerning fire spread over the top of the fire rated wall via the vinyl vapor barrier The test was performed in the worst-case orientation, with purlins framed perpendicular to the wall framing of the one-hour wall Therefore, the same performance can be expected with the wall framed in any orientation with respect to the purlins The test also showed there is no need to cut the vapor barrier, so it can be continuous over the top of the wall The fire test was terminated at hour and forty-one minutes, during which time no flaming occurred on the unexposed surface of the wall or roof at the joint The construction details that successfully prevented flaming over the top of the wall in the test are shown below

used to determine each of the values are given below Using a single point to represent an entire county may produce substantial errors for counties with large areas or closely spaced load contours For example, in Alaska the large political divisions are not conducive to assigning a single value The values given should only be used as a relative guide and the map should be referred to for the appropriate design parameters Snow loads in some areas should be used with caution since local conditions may be more severe than indicated here Also, some regions have very closely spaced contours that could introduce errors Seismic spectral response values were obtained from county-by-county data provided by BSSC that were compiled from the 1997 standard Values were provided by zip code, but were taken at the county seat in order to obtain countywide values for the purpose of this compilation For areas of high seismic activity, this provides a very crude location measure and may yield significantly unconservative ground motion values The recommended approach, in areas of high seismicity, is to use the CD provided with the IBC Additionally, inputting the latitude and longitude of the site yields the most accurate spectral response values The latitude and longitude can be readily obtained from the site street address from a source such as www.mapblast.com Ground snow loads are based on ASCE 7-98 Figure 7-1 (Table 7-1 for Alaska) and are also reproduced in IBC 2000 as Figure 1608.2 (Table 1608.2 for Alaska) Wind velocities are based on ASCE 7-98 Figure 6-1 that is also reproduced in IBC 2000 as Figure 1609 Note that counties that have all or part of their boundary in a "Special Wind Region" are noted with an asterisk after the basic wind speed Special consideration should be given to these regions where records or experience indicate that wind speeds are higher than those reflected in the ASCE or IBC figure or the county listing For wind velocity, values were determined by linearly interpolating between the two contours on either side of a county using the approximate geographic center of the county Ground snow load was not interpolated, that is, the value of the snow load at the point chosen for the county was used Counties that may have areas that fall in an IBC designated wind borne debris region are noted with the basic wind speed in bold type These counties may include hurricane-prone regions which are within one mile of the coastal mean high water line and where the basic wind speed is 110 mph or greater; or where the basic wind speed is 120 mph or greater; or Hawaii The design wind speeds used in these counties, that are generally in areas of closely spaced contours along the coastline, should also be closely evaluated based on where the actual building is located on the ASCE or IBC figures Rainfall intensities were determined somewhat differently The contour maps found in the Weather Bureau Technical Paper No 40 for thirty-minute duration storms with return periods of five and twenty-five years were used The values of the contours were adjusted to reflect 5minute duration by using the factor found in the paper New contours with whole number values were drawn and each county was assigned the value of the next largest contour IX-1 Metal Building Systems Manual IX Climatological Data by County LEGEND S: Ground snow load
