Foundation Slab in Interaction with the Elastic Half-Space

This paper deals with the probability and sensitivity analysis of the foundation slab rested on the layered elastic half-space. The slab has been modeled with shell elements SHEEL185, solid earth masses with solid elements Solid185 with assignment of material properties to individual substrate layers. The CONTA52 was used as a contact element in the ANSYS software. Probability and sensitivity analysis was performed using approximation RSM method (Response Surface Method) for maximum allowable deflection according to the second limiting state. The individual input parameters was varied according to Gaussian, Uniformly or Long-normal probability distribution.
