		<title>Q: Which environmental condition usually controls building material sizes?</title>
		<description><![CDATA[A: Typically wind is the primary (governing) load condition for pole buildings. Snow loading begins to have an important effect at approximately 50 psf and higher.

		<title>Q: What is a shear wall?</title>
		<description><![CDATA[A: A shear wall is a wall that is installed to resist lateral loading such as wind and seismic loads through diaphragm or plate action.

		<title>Q: What is the difference between a cantilevered and diaphragmed building analysis?</title>
		<description><![CDATA[A: A cantilevered building resists lateral loading through post bending only. A diaphragmed building takes advantage of the shear capacity of the wall sheathing to resist lateral loading.

		<title>Q: How does higher than minimum snow loading impact the structural components of a building?</title>
		<description><![CDATA[A: Increased snow loading primarily affects purlins, trusses and rafters. However, it also affects post size, footing size and truss attachment.

		<title>Q: What is the purpose of a footing?</title>
		<description><![CDATA[A: The purpose of a footing is to resist vertical movement of the posts due to vertical loading. The footing prevents the post from sinking into the ground over time.

		<title>Q: What is the most common size of footing for pole buildings?</title>
		<description><![CDATA[A: The most common footing size for a pole building in the northwest is 24&#8243; diameter and 6&#8243; thick. Footings can be larger or smaller as required by load conditions.

		<title>Q: What effects footing size?</title>
		<description><![CDATA[A: Footing size is effected by vertical loading and soil capacity.

		<title>Q: What commonly happens to the building material requirements when one or more walls have large or many openings (doors and windows) in them?</title>
		<description><![CDATA[A: Large doors or openings will increase loading in the diaphragm. The walls may require plywood sheathing. When openings are designed into a building, its capacity to resist lateral (primary wind) loading is reduced.
