Abstract
Some standards for the design of concrete structures (e.g. EC2 and the original ČSN 73 1201-86) allow a structure to be designed by several methods. This contribution documents the fact that even if a structure does not comply with the partial reliability factor method, according to EC2, it can satisfy the conditions during the application of the fully probabilistic approach when using the same standard. From an example of the reliability of a prestressed spun concrete pole designed by the partial factor method and fully probabilistic approach according to the Eurocode it is evident that an expert should apply a more precise (though unfortunately more complicated) method in the limiting cases. The Monte Carlo method, modified by the Latin Hypercube Sampling (LHS) method, has been used for the calculation of reliability. Ultimate and serviceability limit states were checked for the partial factor method and fully probabilistic design. As a result of fully probabilistic design it is possible to obtain a more efficient design for a structure.

Summary
Most of the standards enable the use of a variety of methods for the design of a particular structure. The obtained outcome of these methods depend on n the level of simplification of the calculation within a particular procedure, n the quality of the input data, n the expertise of the engineer, and the amount of time he has available to spend on the structural design. The partial reliability factor method is presently mostly used for the design and review of a structure from the standpoint of ultimate states. This method is used especially for its simplicity and the ease of obtaining input data. Standard [1] alternatively enables the application of probabilistic methods for the design and review of structures. Basic information is mentioned in [1] and [2]
