I'm curious as to how much sway (in degrees) a sky scraper is designed to withstand during high winds or possibly an earthquake. I'm sure each structure may be different so an example of any one structure would suffice. Available links to this answer would be appreciated as well.

  According to a simple calculation, the World Trade Center towers are designed to have a maximum wind-caused sway of approx. 2.5°.
