Document Summary
There"s a lot we don"t know about the loading and the properties of the materials. So, we need a step in our design process that allows us to consider for the uncertainty. Kind of nuance b/c we lump into one where there is a lot of range. This could end up with a structure that is too unsafe or one that is too conservative. "the focal points are where the behaviour of the structure changes and the new behaviour ceases to perform the function" "it"s very unlikely that all of these loads will happen as once and the building code compensates for that"] Most of our live loads act in a vertical direction. It can act vertically, laterally, or any combination in between. Due to the boundary layer effects of the surface of the earth, the higher you go, the higher the wind strength will be.
