This presentation mainly includes following contents:
Background: There is the largest scale infrastructure such as the large-span bridges etc. in the world to have been building in China in recent 20 years so that it is just the chance to employ and develop the approaches and technology of the life-cycle performance monitoring, evaluation, control and design of infrastructure. Monitoring of Life-cycle Performance: What is the health of infrastructures? It would includes all factor changes resulting in the deterioration of the performance such as safety, serviceability, durability, sustainability of infrastructures. Structural health monitoring plays more and more important role in the life-cycle performance evaluation and design of infrastructure.
Data Mining and Performance Evaluation based on SHM: Based on SHM, it would be more possible to model the real long-term environmental actions and the deterioration of material, members and structures. Multi-scale models and their updating based on SHM would provide important base for the life-cycle performance evaluation of infrastructure.
Design of Life-cycle Performance: The real long-term environment actions such as fatigue loading, temperature changing and acid, alkali, chloride actions etc, the deterioration of material, members and structures such fatigue, corrosion, aging etc and their relationships are the important base for the life-cycle performance design of civil infrastructures.
Challenging Issues of Disaster, Damage and Health Monitoring: It includes some challenging issues of earthquakes disaster, wind effects, fatigue and durability monitoring.。
