Minimal but disturbing, building vibration can be dampened ...
· Minimal but disturbing, building vibration can be dampened. Since the 1970s, floor slabs have become thinner and lighter, and column spacing has increased, with typical spans of 40 feet rather than 25 feet. As a result, newer buildings often do not dampen vibrations as well as older ones. Vibration can now be a source of anxiety for occupants.

In both cases, as before, iωwe assume a solution of iωthe form x 1(t) = X 1e tand x 2(t) = X 2e t. However, as we will see, in this case, we will obtain two possible values for ω2; both will be real; we will take only the positive value of ω itself. These will be the two vibration modes of this two degree of freedom system. These
