The proposed research will include experimental and analytical works to study explicitly the interface behavior and its effect on the global material behavior. Principal Investigator expect to quantify the role of interface strength on the behavior and provide knowledge that will be essential in engineering the difficulty in high strength concrete. Thus, the proposed research is expected to have a direct impact on the production and use of high strength concrete in structures in efficient, economical, and safe manner. Results of the proposed work will provide insight into the deformation behavior and failure mechanisms, and will allow the development of methods for predicting failure in high strength concrete structures, thus increasing the safety in engineering design applications.

拟议的研究将包括实验和分析工作，以明确研究界面行为及其对整体材料行为的影响。 首席研究员希望量化界面强度对行为的作用，并提供在解决高强度混凝土困难方面至关重要的知识。 因此，所提出的研究预计将以高效、经济和安全的方式对结构中高强度混凝土的生产和使用产生直接影响。 所提出的工作结果将提供对变形行为和失效机制的深入了解，并将允许开发预测高强度混凝土结构失效的方法，从而提高工程设计应用的安全性。
