Limit and shakedown analyses allowing for limited ductility

建立在极限和安定概念基础上的结构完整性直接评估方法提供了关于结构失效荷载的重要信息。该项目旨在通过将有限延性的影响纳入分析来克服这种方法的严重缺陷。将开发新的配方和高效的算法。这些工具将用于更好地了解有限延性的含义，这对于在复杂荷载下对有限延性结构进行适当的安全评估至关重要。这种能力在基础设施设计以及航空技术等战略领域都很重要。

The integrity assessment of structures by direct methods, founded on limit and shakedown concepts, provides vital information about their failure loads. This project aims at overcoming a severe shortcoming of such approaches by incorporating the effects of limited ductility into the analyses. Novel formulations and efficient algorithms will be developed. These tools will be used to provide a better understanding of the implications of limited ductility, vital to a proper safety assessment of limited ductility structures under complex loadings. Such a capability is important in infrastructure design as well as in such strategic areas as the aeronautical technologies.
