  1. Brief Introduction of DECISEW in China (Disaster Evolution of Civil Infrastructure under Strong Earthquake and Wind) Jinping Ou Dalian University of Technology Harbin Institute of Technology Aug. 8, 2013

  2. The Major Research Program of NSFC 国家自然科学基金重大研究计划 Disaster Evolution of Civil Infrastructure under Strong Earthquake and Wind (DECISEW) 重大工程的动力灾变 Research Period 研究周期:2008.1-2015.12 Total Funding 资助金额: ¥214Million ¥190Million (General Projects) ¥ 6+18Million(International Cooperation) Reporter: Jinping OU/欧进萍,DUT & HIT

  3. Infrastructures 重大工程 Civil and Hydraulic Infrastructures Damage Evolution of Civil Infrastructure: Damage evolution and collapse mechanism of civil infrastructure under dynamic actions of earthquake and Hurricanes 重大工程的动力灾变:研究重大工程在强地震、强/台风动力作用下的损伤演化过程与倒塌破坏机制 桥梁 建筑 隧道 • Long Single and Multiple Span Bridges 长大桥梁 • Huge Buildings such as tall buildings, large space structures and huge underground structures大型建筑(超高建筑、大型空间结构、大型地下建筑) • High Dams 高坝 大坝 城市

  4. 上海金茂大厦 南京长江三桥 国家大剧院 三峡大坝 秦岭隧道 • There is the largest scale infrastructure in the world to have been building in China in recent 20 years • 我国重大工程建设的宏大规模已居世界之首 • A lot of infrastructure have been built • 已经建成一大批重大工程 • 6 of highest buildings in the world, 492m • 世界前10座最高建筑,我国6座 (492m) • 7 of largest span cable-suspended bridges in the world, 1088m • 世界前10座最大跨度斜拉桥,我国7座 (1088m,在建) • 3 of largest suspended bridges in the world, 1490m • 世界前10座最大跨度悬索桥,我国3座 (1490m) • The largest hydraulic project in the world: The Three Gorge Project • 世界上最大规模的水利工程——我国三峡工程 • The highest dam in the world: 292m, 305m • 世界上最高的拱坝——我国小湾(292m)、锦屏(305m)

  5. 上海环球金融中心 广州 新电 视塔 苏通大桥 小湾大坝 • And more infrastructure to have been building or to be built, such as the highest building, TV tower, dam and the largest span cable-suspended bridges • 正在或将要建设更多的重大工程 • ——世界上最高的建筑、电视塔、拱坝以及跨度最大的斜拉桥等 The infrastructure to be built each year in China exceeds the summation of all other countries in the world 我国每年以土木水利工程为主的基础设施建设规模已经超过世界上其他所有国家的总和

  6. The objective: Facing 1000m-span bridges, 500m-height tall buildings, 300m-hight dams Key issues: Simulation and verification of Strong earthquake and typhoon fields Simulation and verification of nonlinear dynamic damage and collapse of infrastructure Failure model optimization and control of infrastructure 面向重大工程——千米级大桥、五百米级超 高层建筑、三百米级高坝等 聚焦重大科学问题 ——强地震动场和强/台风场模拟、集成与验证; 重大工程结构构件、结构整体及其耦合介质的非线性动力损伤演化与灾变过程模拟、集成与验证; 重大工程结构动力灾变的失效机理、失效模式优化与灾变控制

  7. Simulation, analysis and design of civil infrastructure under strong earthquake or wind could be realized not only possibly, but also more accurately and more finely • How to get more accurate action and models of strong earthquake ground motion and Hurricane velocity fields? • How to establish the fine computational models of infrastructure such as huge bridges, buildings and dams? • How to numerically, physically or hybridly simulate the damage evolution and collapse process of infrastructure such as huge bridges, buildings and dams? • How would the properties and models of structural materials, members and systems effect on the damage evolution and collapse process of infrastructure such as huge bridges, buildings and dams? • How to improve and even optimize or control the damage evolution and collapse modes of infrastructure such as huge bridges, buildings and dams?
