“…In Ronold and Larsen (2000) the fi rst-order reliability method (see e.g. Madsen et al ., 1986) was used for the estimation of reliability in all cases, through the implementation of the commercially available code PROBAN (Tvedt, 2006), while the commercially available code STRUREL (Gollwitzer et al ., 2006) has been implemented in FAROW (Winterstein and Veers, 2000), a more general tool for fatigue calculations and reliability estimations of wind turbine components, which focuses on modelling the interaction between the environment, the load response to the environment and the cumulative damage process underlying the lifetime calculation. The applications presented in these earlier works (see e.g.…”

“…ProbCalc is a software application which is still under development. It is rather easy and simple to implement quite a complicated analytical transformation model of a probabilistic task defined in a character form or as a dynamic DLL library similarly as in Tvedt [12], Thacker et al [13], and Cervenka et al [14]. A lite version of this software can be downloaded from the webpage http://www.fast.vsb.cz/popv/ [15].…”

The load-carrying system of each construction should fulfill several conditions which represent reliable criteria in the assessment procedure. It is the theory of structural reliability which determines probability of keeping required properties of constructions. Using this theory, it is possible to apply probabilistic computations based on the probability theory and mathematic statistics. Development of those methods has become more and more popular; it is used, in particular, in designs of load-carrying structures with the required level or reliability when at least some input variables in the design are random. The objective of this paper is to indicate the current scope which might be covered by the new method—Direct Optimized Probabilistic Calculation (DOProC) in assessments of reliability of load-carrying structures. DOProC uses a purely numerical approach without any simulation techniques. This provides more accurate solutions to probabilistic tasks, and, in some cases, such approach results in considerably faster completion of computations. DOProC can be used to solve efficiently a number of probabilistic computations. A very good sphere of application for DOProC is the assessment of the bolt reinforcement in the underground and mining workings. For the purposes above, a special software application—“Anchor”—has been developed.

“…However, for complex mechanical models combining several types of element and problem (ageing chemical-mechanical behaviour of concrete for example), these implementations become somewhat cumbersome. For the sake of simplicity, general purpose reliability programs often resort to the finite difference method for computing the gradient vector [4,[14][15][16][17], which remains attractive and easily practicable:…”
