Design, Evaluation and Retrofit of Concrete Infrastructure

这项研究计划的目的是改进新混凝土结构的设计，并开发评估和改造缺乏混凝土基础设施的技术。这项研究将有助于开发抗震桥梁设计的新方法。该研究还将开发改进的方法，用于分析设计或施工缺陷的旧桥梁和建筑物。将研究的方面包括无剪力加固厚板的性能，以及通过添加剪力加固厚板。将进行实验和分析研究，以审查旧建筑物结构元件的复杂应力流动区域的缺陷。另一个目标是开发行为模型，以预测由于使用除冰盐而导致混凝土劣化的停车场板的性能。

This objective of this research program is to improve the design of new concrete structures and to develop techniques for the evaluation and retrofit of deficient concrete infrastructure. The research will aid in the development of new approaches for the design of bridges to resist earthquakes. The research will also develop improved methods for analysing older bridges and buildings that have design or construction deficiencies. Aspects that will be studied include the performance of thick slabs without shear reinforcement, as well as the strengthening of thick slabs by adding shear reinforcement. Experimental and analytical studies will be carried out to examine deficiencies in regions of complex flow of stresses in structural elements in older buildings. Another objective is to develop behavioural models to predict the performance of parking garage slabs that have been subjected to concrete deterioration due to the use of de-icing salts.
