framing every 2'. Or 4' with blocking spaced as noted for
purlin & girt spacing below.
Above is roof layout.
Girts on walls spaced every 4 feet.
Layout above will support
a 25 lb. load. For 30 lb. load position mid purlins every 3
ft. For 40-50 lb. load position all purlins every 2 ft. To
increase load carrying capability add blocking on top of rafters.
Increased wind load,
Basically increase screw attachment pattern so wind does not pull
sheet off frame. Make sure to use our Screws with 3/4" sealing washers and consult with us in hurricane zones.
Structural Loads are
stresses to structure from external or internal
forces.
• Dead loads are
gravity loads that are constant throughout the structure's life.
These include equipment such as fans, heaters and plants suspended
from the frame. • Live loads are
temporary, such as snow loads and wind
loads. • Snow loads determined by factors influencing snow & ice accumulation on
the structure. Snow loads vary
considerably by geographic location. Ask your local bldg. dept.
for snow load in your area. (
12 inches of light, fluffy snow or 2 to 4 inches of heavy, wet
snow = about 5 lbs per sq. ft.)
