Course overview and goals

Infrastructures are subjected to various natural hazards such as ground motions, tsunami, torrential rains, floods, typhoons over their life-cycles. It is necessary to plan, design and maintain the structures so that they can continue their functions even under such hazards. From the viewpoint of ensuring the safety and reliability of structures, it is sufficient to control the possibility of occurrence of the limit states. On the other hand, infrastructures do not function as stand-alone structures, but as a structural system or network consisting of a group of individual structures, such as road networks, railway network and water supply networks. Furthermore, in today's highly networked society, including its dependence on electric power, the impact on users and economic activities when structures and structural systems are damaged is becoming more complex and significant. Therefore, there is an increasing needs to quantify the effects of degree of damage and functional degradation of structures corresponding to limit states, using the concepts of risk and resilience, and to apply them to the management of structures.
In this course, items related to the assessment of reliability, risk, and resilience of structures and structural systems will be covered. The aim of this course is to develop the basic ability to apply such concepts and related knowledge to structures and structural systems, and to develop discussion from a comprehensive perspective through presentations toward building and maintaining a more resilient society.

Course description and aims

Students are expected to obtain the following abilities:
1. the ability to explain the relationship between natural hazards and the limit states, degree of damage, and functional loss that can occur to structures and infrastructures.
2. the ability to use the concepts of risk and resilience to make discussion for building and maintaining a more resilient society.
