Summary

The risk assessment of foundation settlement due to external loading especially in the case of critical structures, i.e. nuclear reactors or oil silo structures is a very important issue. Assuming that, even, small deformation of soil may lead to catastrophic results, it is useful to estimate according to the uncertain conditions, the probability of the settlements exceeding the critical limits. To quantify the uncertainty of the soil a new algorithm of RFEM is developed using the circulant embedding method. An example of a plane-strain strip load on a semi-infinite elastic foundation is presented and the results of the settlement are compared to those obtained from the closed form solution method. A close matching of the two is observed.
