The building I work in has expansion joints built in every 5th floor. This allows the building to sway. I work on the 12th floor and it's very windy out today. The lights above my desk are swinging. The creaks in the walls don't bother me unless a severe thunderstorm is moving thru. Then I get nervous.
This happened to our bldg. after a bad storm in April 2006.
