Effects of Asymmetry on Dynamically Loaded Foundations

Dynamically loaded foundations are subjected to long-term dynamic loads besides static loads. Dynamic loads require control of the vibration amplitudes to not to exceed the permissible limits as well as avoiding from resonance. Considering these circumstances, symmetric system designs are done. System symmetry is provided if the system’s center of gravity and the support’s center of rigidity are on the same vertical axis. However, this symmetry situation always cannot be maintained after the design. In this study, effects of machine placement and support rigidity change induced deviations from symmetry on vibrations of the dynamically loaded foundation systems are investigated.
