Large earthquake is recognized as the greatest natural hazard in major urban centres across Canada. A research program is proposed to develop advanced seismic assessment methodology and tools for more accurate evaluation of the seismic performance of complex bridges, and innovative techniques and cost-effective solutions for mitigation of the seismic risk of reinforced concrete shear wall structural systems. The goal of the research program is to enhance the safety and security of Canada's critical infrastructures, contribute toward the development and advances of performance-based earthquake engineering and design of safer and more loss-resistant infrastructures. The research program consists of three parts: (i) Seismic modeling and analysis of bridges; (ii) Network hybrid testing of large structures; and (iii) Seismic repair and strengthening of reinforced concrete shear walls using a novel FRP-tube anchor system.

大地震被认为是加拿大主要城市中心最大的自然灾害。提出了一项研究计划，以开发先进的抗震评估方法和工具，更准确地评估复杂桥梁的抗震性能，以及创新技术和成本效益的解决方案，以减轻钢筋混凝土剪力墙结构系统的地震风险。 该研究计划的目标是加强加拿大关键基础设施的安全和保障，促进基于性能的地震工程的发展和进步，以及更安全和更抗损失的基础设施的设计。 研究计划包括三个部分：（i）桥梁的地震建模和分析;（ii）大型结构的网络混合测试;以及（iii）使用新型FRP管锚系统对钢筋混凝土剪力墙进行抗震修复和加固。
