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.

混凝土样品在常规试验中所经受的热负荷不能精确地和独立地控制。本计画借由一种新的热负荷技术，重新检视混凝土在火灾下的性能。通过建立热通量作为一个参数的研究，混凝土性能在广泛的火灾条件下，预计将更好地量化，最终导致一个可靠的性能为基础的设计混凝土结构。预期的成果包括改进对火灾和其他荷载联合作用下混凝土性能的理解，基本混凝土性能和本构关系的适当数学模型，以及真实的火灾暴露下混凝土性能的设计建议。
