The basis of ULS reliability theory of are the definitions of characteristic and desing (i-e. subsitutive) values differing substantially in individual countries in the formulation of selection from random sets and in the systems of partial factors. An important discrepancy can be found in the concept of the respective EUROCODE 7-1 and \u010CSN in definitions of substitutive values. The problem is higly topical due to the planned obligatoriness of EC 7-1 (also in CzR) in 2005 and the necessity of drafting the National Annex. The results of contemporary reliability theory of LSD of granular materials are problematic, as the designs are considarably conservative and ineffective. Therefore, the project concentrates on the key issue definitions and factors. The results can be used directly in standardization."@en . .
