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)

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

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

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

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?
