Major cities worldwide are experiencing a rapid urbanization where both population and infrastructure are growing at an unprecedented rate. These cities rely on various public transportation services (buses, trains, ferries, bridges, and tunnels), service centers (hospitals, fire halls, and police stations), communication networks (cables and telephone lines), and utility services (water, sewer, electric, and fuel lines). These vital infrastructures are commonly known as lifelines. In the event of a major earthquake, lifeline failure will impede the city's ability to function. Business downtime and prolonged recovery will lead to significant financial losses and eventually break down the urbanization. In 2011, the Christchurch earthquake in New Zealand destroyed the central business district (CBD) which resulted in $20 billion USD financial losses and forced the entire CBD shut down for 28 months. This prolonged disruption significantly affected the city's ability to recover and led to massive emigration. The seismic vulnerability in New Zealand is very similar to many urban cities around the Pacific Rim, including Metro Vancouver. Geological evidence shows that magnitude 9 or greater earthquakes are likely to happen in this region. Preparing for the next significant yet unavoidable earthquake must be the highest priority for the city. In the past 6 years, the applicant has led his research team in developing advanced simulation tools to quantify seismic vulnerability of critical infrastructures and developing novel structural components to improve structural performance during strong earthquake shaking. The proposed research program aims to expand the knowledge to develop a robust program for an entire city's lifelines. The long-term goal of the program is to ensure continuous function of lifelines during the shaking and recovery phases of earthquakes. The program will be developed through the following four research areas using the City of Vancouver as the model city: A) Develop efficient and reliable assessment tools to identify critical lifelines; B) Develop advanced experimental methods to examine the seismic behaviour of critical lifelines; C) Develop advanced numerical methods to simulate the seismic responses of critical lifelines; D) Develop and implement resilient lifelines. Upon completion of the research, a team of highly-qualified engineering personnel with the ability to use the state-of-the-art engineering technologies to evaluate and retrofit existing lifelines will be created. The team will be the next generation leader in the development and implementation of advanced structural engineering technologies to design and safeguard the Canadian infrastructures.

全球主要城市正在经历迅速的城市化，在这种城市化中，人口和基础设施都以前所未有的速度增长。这些城市依靠各种公共交通服务（公共汽车，火车，渡轮，桥梁和隧道），服务中心（医院，消防厅和警察局），通信网络（电缆和电话线）以及公用事业服务（水，下水道，电力和燃油管线）。这些重要的基础设施通常称为寿命。如果发生重大地震，生命线失败将阻碍城市的运作能力。业务停机时间和延长的恢复将导致重大财务损失，并最终破坏城市化。 2011年，新西兰的基督城地震摧毁了中央商务区（CBD），这导致了200亿美元的财务损失，并迫使整个CBD关闭了28个月。这种长时间的干扰极大地影响了该市康复的能力并导致大规模移民。新西兰的地震脆弱性与包括温哥华大都会在内的太平洋地区的许多城市城市非常相似。地质证据表明，该地区可能发生9级或更大的地震。为下一个重大但不可避免的地震做准备必须是该市的最高优先事项。在过去的6年中，申请人领导了他的研究团队开发高级模拟工具，以量化关键基础设施的地震脆弱性并开发新的结构组件，以在强烈地震摇动期间改善结构性绩效。拟议的研究计划旨在扩大知识，以为整个城市的寿命制定强大的计划。该计划的长期目标是确保在地震的震动和恢复阶段中终生的连续功能。该计划将通过以下四个研究领域开发，使用温哥华市作为模型城市：a）开发高效可靠的评估工具来识别关键的寿命； b）开发先进的实验方法来检查关键寿命的地震行为； c）开发高级数值方法来模拟关键寿命的地震反应； d）开发和实施弹性寿命。研究完成后，将创建一支高度合格的工程人员，能够使用最先进的工程技术来评估和改造现有的救生线。该团队将成为高级结构工程技术开发和实施的下一代领导者，以设计和维护加拿大基础设施。
