Unified nondeterministic dynamic safety assessment of softening structures

本项目旨在开发一种用于软化结构动态安全评估的高性能工具。表现出软化的结构，无论是在本构水平或结构水平的评估，是必不可少的设计和修复的目的，特别是当不可避免的不确定性，在系统参数需要考虑。这个项目的目的是开发一个先进的和统一的框架，可以模拟随机和非随机过程为这些目的。一个先进的混合有限元模型支撑这个框架，制定和解决方案的算法是基于数学规划形式主义。所开发的计算工具将能够执行纯随机，纯非随机，混合不确定性分析和结构的动力可靠性评估。

This project aims to develop a high-performance tool for the dynamic safety assessment of softening structures. The assessment of structures that exhibit softening, either at constitutive level or structural level, is essential for design and rehabilitation purposes, especially when the inevitable uncertainties in the system parameters need to be accounted for. This project aims to develop an advanced and unified framework that can model both stochastic and nonstochastic processes for these purposes. An advanced mixed finite element model underpins this framework, and both formulation and solution algorithms are based on mathematical programming formalism. The developed computational tool would be able to perform pure stochastic, pure nonstochastic, hybrid uncertain analyses and dynamic reliability assessment of structures.
