【英文介绍】

FReET?is a multipurpose probabilistic software for statistical, sensitivity and reliability analysis of engineering problems. It allows to simulate uncertainties of the problem at random variables level (typically in civil/mechanical engineering – material properties and loading, geometrical imperfections).

?

FReET?includes state-of-the-art probabilistic simulation algorithms to compute the probabilistic response and reliability. It is developed in C++ and optimized for speed.

?

FReET?is a modular computer system for performing probabilistic analysis of engineering problems developed mainly for computationally intensive deterministic modeling such as FEM packages, and any user-defined subroutines. Therefore small-sample simulation techniques are preferred. The most successful FEM integration represents the combination with nonlinear fracture mechanics software for analysis of concrete structures ATENA.

?

FReET-D?(the acronym for?Feasible?Reliability?Engineering?Tool for?Degradation effects assessment) is an optional modul for modeling of degradation phenomena in concrete structures due to environmental actions, for probabilistic assessment of service life.
