The fully probabilistic approach and partial reliability method were used for checking the reliability of a pole. The influence of the concrete used (non fibre and fibre reinforced concrete – 2 alternatives) and reinforcement type (prestressed and non-prestressed) were taken into account in the optimisation process. The statistical distribution of the chosen random quantities (material and geometrical characteristics, horizontal loading, uncertainties of the resistance model) was taken from the recommendation of the JCSS and from the producer´s measurements. The Latin Hypercube Sampling (LHS) modification of the Monte Carlo simulation method was used in the case of using probability based design.
The proposed method allows the checking of the best available material and reinforcement alternative for the designed structure.
The mechanical properties of concrete are significant especially as regards the serviceability limit state of the designed pole. Using fibre reinforced concrete is an effective solution.
