Cooperative Laboratory(Joining and Welding Reasearch Institute)

Department of Dependability and Optimum Design, Research Division of Functional Assessment
Department of Dependability and Optimum Design, Research Division of Functional Assessment In evaluating the reliability of the structures, this department investigates not only the conventional optimization for the safety and durability in constructing steel structures but also the reliability (dependability) including the maintenance, repair/reinforcement, and evaluation of lifetime considering cultural science and social science. Moreover, by researching on the procedure of safely demolishing structures that have completed their lifetime, the circulating loop in which the members or units are reused is concretized.
The department aims to establish the evaluating methods to satisfy the high accuracy and the high quality in cutting, processing, and assemblage of “products of steel structures” based on the dependability in the circulating loop containing the maintenance, repair/reinforcement, and evaluation of lifetime.
Current Research Subjects
1. Monitoring of damages and evaluation of the lifetime of existing steel structures
2. Evaluation of the weldability and joint quality of steel for long-term use
3. Soundness diagnosis of structural members and joints
4. Development of life extension technology for steel structures
5. Elucidation of elastic-plastic behavior in thermal processing
6. Prediction, control, and prevention of welding imperfections
