FReET-工程概率分析软件

FReET是一款用于工程问题统计、灵敏度和可靠性分析的多用途概率软件。它允许在随机变量水平上模拟问题的不确定性（通常在土木/机械工程中——材料特性和载荷、几何缺陷）。

FReET包括先进的概率模拟算法，用于计算概率响应和可靠性。它是用C++开发的，并针对速度进行了优化。

FReET是一个用于对工程问题进行概率分析的模块化计算机系统，主要用于计算密集型确定性建模，如FEM包和任一用户定义的子程序。因此，首 选小样本模拟技术。成功的有限元集成代表了与非线性断裂力学软件ATENA的结合，用于混凝土结构的分析。

FReET-D（退化效应评估的可行性可靠性工程工具的缩写）是一个可选模块，用于对环境作用引起的混凝土结构退化现象进行建模，并对使用期限进行概率评估。

【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.
