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.

这项研究计划的目标是改进新混凝土结构的设计，并开发评估和改造不足的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。这项研究还将开发改进的方法，用于分析存在设计或施工缺陷的旧桥梁和建筑。将研究的方面包括没有抗剪钢筋的厚板的性能，以及通过添加抗剪钢筋对厚板进行加固。将进行实验和分析研究，以检查旧建筑结构构件中应力复杂流动区域的缺陷。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库楼板的性能。
