Here is a question for the engineers and architects out there. How do you calculate the load that the environment places on a structure and is this considered a dead load or a live load?
Here is what I mean. Say you have a bridge. It is going to get hit by a certain wind load though its entire life. In the event of a heavy storm this could be significant. If you have a tall building it will also get hit with wind and its rood will collects rain and snow. All of these factors place a strain on a structure that engineers must have to account for. How do they do this, how can you predict the wind? I'm really hoping someone can pick this question up because it really baffles me.
