“…The course of the linear regression exhibits a slight drop of the mean value, see Figure 3. Figure 4 displays the distribution of the probability density for the end point of the time series (obtained via the HistAn tool [28]). The annual average deposition rate of the concentration of sulfur dioxide in the air experienced a significant change over the past 50 years [26,27].…”

The design, construction, and maintenance of steel structures must be carried out in a way that ensures they will be able to reliably operate for the whole duration of their planned service life. To ensure sufficient durability, it is necessary to determine and evaluate the characteristics of the appropriate environment in which the structure will be placed. This submission focuses on the specific environment surrounding roads that are treated with de-icing salts during winter maintenance. It investigates the dependency between corrosive damage to the structure and the relevant parameters of the environment. Basic corrosive factors include temperature, relative humidity, deposition of chlorides and sulfur dioxide, precipitation, the pH of precipitation as well as many other parameters. An accurate estimate of corrosive damage requires an analysis of the long-term trends in concentrations of individual corrosive factors, while respecting their randomly varying attributes. The article, hence, introduces and evaluates stochastic prediction models that are based on long-term programs focusing on the evaluation of the corrosive aggressiveness of the environment, while taking into account random variations of the nature of the input parameters. The use of stochastic prediction models allows us to perform sensitivity analysis that can determine the impact of specific corrosive factors on the corrosive damage caused to the structure. The article is supplemented by sensitivity analysis focusing on an evaluation from the effects of the deposition of chlorides on the corrosive damage to steel bridge structures. The analysis was carried out using data obtained from experimental measurements of the deposition rates of chlorides in the vicinity of roads in the Czech Republic.

This paper deals with the use of probabilistic methods in the reliability assessment of water vapor condensation on the building structures surface. To calculate the resulting probability of failure it was used original and newly developed Direct Optimized Probabilistic Calculation – DOProC method, which has been successfully applied in the software system ProbCalc. To solve this probabilistic computation tasks, this would appear to be very effective and accurate. When calculating the resulting probability of failure there was also taken into account the statistical dependence of the random input variables, which were expressed probabilistically based on long-term monitoring of the assessed building.

When a tank containing liquid vibrates, the liquid exerts hydrodynamic effects on the solid domain of a tank. In the case of roof tanks, a large sloshing wave will impact the wall or roof of the tanks and may cause extensive damage or failure of the tanks. This paper provides the theoretical background of simplified seismic analysis of liquid storage cylindrical ground -supported tanks, and it documents the seismic effect of input motions characteristics on fluid sloshing behaviour.
