<br />Notes:
<br />1) For effective areas between those given above the load may be interpolated, otherwise use the load
<br />associated with the lower effective area.
<br />2) Plus and minus signs signify pressures acting toward and away from the building surfaces, respectively.
<br />3) See pressure zone diagrams above for corresponding zones.
<br />4) Roof coverings, finishes, etc.. Shall be design for the full negative design pressure.
<br />5) Roof framing members shall be designed to resists the net uplift design pressure specified.
