Abstract
The dynamic characteristics are examined of buildings constructed on soft soil in Ashkhabad. The frequency spectrum and damping are evaluated with respect to soil conditions. It is determined that for buildings up to 5 stories high, damping is strongly nonuniform. Modal first-mode damping is 3-4 times greater than for the rest. For high-rise buildings, modal damping values were close, which was the result of pivoting foundation vibrations and exposure to Rayleigh surface waves. Calculation programs that do not consider nonuniform damping are proposed to be used to assess damping in the first approximation.
