Seismic rotations of soil give a notable contribution in the dynamic response of structures built on soft soils and sensitive to the wave effect of seismic load. These effects lead to torsion and increasing of accelerations in the angular elements of the structure. They reduce the effectiveness of seismic isolation, cutting the strength reserve of the bearing elements. The paper presents the results of research aimed at assessing the influence of soil rotation motions on the value of accelerations emerging in the angular points of the seismically isolated structure positioned on the pendulum bearings.
