Fire performance of concrete using novel fire testing

在常规试验中，混凝土试样所经受的热载荷不能准确、独立地控制。该项目通过使用一种新颖的热加载技术，旨在重新审视混凝土在火灾中的性能。通过将热流密度作为研究参数，可以更好地量化大范围火灾条件下的混凝土性能，最终实现可靠的混凝土结构性能设计。预期的结果包括提高对混凝土在火灾和其他载荷下的性能的理解，对混凝土基本特性和本构关系的适当数学模型，以及在真实火灾暴露下混凝土性能的设计建议。

Thermal loading experienced by concrete samples in conventional tests cannot be accurately and independently controlled. This project, through using a novel thermal loading technique, aims to re-examine the performance of concrete in fire. By establishing the heat-flux as a parameter of study, concrete performance under a wide range of fire conditions is expected to be better quantified, eventually leading to a reliable performance-based design of concrete structures. Expected outcomes include improved understanding of concrete performance under combined fire and other loadings, appropriate mathematical models for fundamental concrete properties and constitutive relations, and design recommendations for concrete performance under real fire exposures.
