Coupled effects of stress and temperature changes on concrete structures

混凝土结构通常会受到应力和温度变化的共同影响，这是非常重要的，需要适当考虑。然而，考虑到这些影响的现有工程模型基本上仍然是经验的，这必然限制了它们的预测能力。这项研究旨在通过一种创新的方法来检验这种耦合效应，该方法将原始的基于物理的分析研究与新颖的测试和先进的数值工作相结合。预期结果包括一个强大而简单的工程模型，以及合理设计结构的指导方针(包括。混凝土在火灾中剥落)，并适当考虑到这种耦合效应，从而能够在节省大量成本的情况下实现更坚固的结构。

The coupled effects of stress and temperature changes that concrete structures are commonly subject to are significant and need to be properly accounted for. However, existing engineering models accounting for these effects remain essentially empirical, necessarily limiting their predictive capability. This research aims to examine such coupled effects using an innovative approach combining original physical-based analytical study with novel tests and advanced numerical work. Expected outcomes include a robust yet simple engineering model, and guidelines for rational design of structures (incl. concrete spalling in fire) with due account for such coupled effects, thereby enabling to achieve more robust structures at substantial cost saving.
