Popis: The major objective of this paper is to quantify the effects of uncertainties in soil properties and loading conditions on the performance of rocking foundations during seismic loading. Probabilistic numerical simulations were carried out using a validated soil-foundation Contact Interface Model in OpenSees finite element framework. Results indicate that for relatively larger static vertical factor of safety systems, the moment capacity of rocking foundations mainly depends on the applied vertical load on the foundation as opposed to the bearing capacity, while the energy dissipation and settlement are more sensitive to initial vertical stiffness of soil-foundation system and applied vertical load.
