Mathematical model of structure located on various systems of seismic isolation such as laminated rubber bearings and pendulum bearings are considered. This model takes into account torsion of superstructure caused by rotational component of seismic excitation. Rotational component of seismic excitation reflects the wave nature of earthquake. This paper illustrates the torsional response of isolated structure.
