Mean roof height mrh ft this is needed to determine canopy pressure.
This table compares results between asce 7 10 and asce 7 16 based on 140 mph wind speeds in exposure c using the smallest ewa at 15 foot mean roof height in zone 2.
A simplified procedure and an analytical procedure.
Explanation of asce 7 05 asce 7 10 and asce 7 16.
Visually aama tir a15 14 illustrates the mean roof height as per the image below where h on the sloped roof is ridge height eave height 2.
Asce 7 10 provides two methods for wind load calculation.
Pressure increases vary by zone and roof slope.
Asce 7 16 also.
Interior field perimeter and corner see figure 3.
Asce 7 05 and asce 7 10 have three roof zones.
Mean roof height as defined in asce 7.
Asce 7 16 added another zone and it presents the potential to have four roof zones.
Gc p can be determined for a multitude of roof types depicted in figure 30 4 1 through figure 30 4 7 and figure 27 4 3 in chapter 30 and chapter 27 of asce 7 10 respectively.
The simplified procedure is for building with a simple diaphragm roof slope less than 10 degrees mean roof height less than 30 feet 9 meters regular shape rigid building no expansion joints flat terrain and not subjected to special wind condition.
Figure asce 7 95 external pressure coefficients gcp for loads on building components and cladding for enclosed or partially enclosed buildings with mean roof height h less than or equal to 60 ft 18 m.
We shall only calculate the design wind pressures for purlins and wall studs.
The wind speeds correspond to 3 second gust speeds at 33 ft above ground for exposure c category.

For intermediate values of vasd the height associated with the next higher value of vasd shall be used or direct interpolation is permitted.
See help glossary link above for explanation.
This is the average roof height of the main residence from the peak to the eave.
Field perimeter and corner see figure 2.
Mean roof height asce 7 per asce 7 the mean roof height h is defined as the average of the roof eave height and the height to the highest point on the roof surface except that for roof angles of less than or equal to 10 the mean roof height is permitted to be taken as the roof eave height.
The dimensions of the zones are mostly determined by a building s length and width.
