Seismic risk assessment and mitigation of critical structures

点击翻译按钮获取中文摘要

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.
