Venue: Phuket, Thailand
Mini-Symposium within International Conference on Computational & Experimental Engineering and Sciences.
Limit states and risk-based approaches are today core methodologies for design and safety assessment of newly-built structures and also for health monitoring of aging structures. While in service, structures are subjected to various phenomena arising from service requirements which may range from routine to extreme or even accidental. As the environmental and operating conditions become harsher, the structures shall be more likely subjected to nonlinear structural consequences in conjunction with limit states that are conditions in which the structures fail to perform their intended functions designated beforehand.
It has now been recognized that the limit states are much better basis for structural design and strength assessment than the allowable working stress because it is not possible to determine the true margin of structural safety as long as the limit states remain unknown. Four types of limit states are relevant, namely serviceability limit states (SLS), ultimate limit states (ULS), fatigue limit states (FLS), and accidental limit states (ALS).
As structures get older, they suffer various types of degradation including corrosion andfatigue cracking damage. Health monitoring or condition assessment of aged structures isrequired for keeping structural integrity and/or for structural longevity in association withrelevant schemes of inspection and maintenance. Within the framework of health monitoring of aging structures, limit states and risk-based approaches also play a key role.
According to the Murphy ’s Law, if anything is wrong then it will. This would mean that a risk always exists wherever there are potential hazards. In the design and operation of many types of structures, there are a number of hazards that must be dealt with in the process of risk assessment and management.
Although substantial efforts have been directed toward the application of limit states andrisk-based approaches, there are still a large number of challenging issues to be resolved. The main objective of this symposium is to provide a forum in which recent advances and future trends together with challenging issues on limit states and risk-based approaches are discussed and shared by scientists, technocrats, and practicing engineers.
Topics of interest may include but are not limited to:
- Serviceability limit states
- Ultimate limit state states
- Fatigue limit states
- Accidental limit states
- Health monitoring (condition assessment) of aging structures
- Hazard identification and frequency analysis
- CFD simulations on fire and explosion
- Consequence analysis
- Structural reliability
- Risk assessment and management
- Risk-based design
- Risk-based safety assessment- Risk-based inspection and maintenance
