Seismic disaster prevention technologies for infrastructures and lifeline network systems in highly congested modern cities; seismic risk assessment and retrofitting investments for existing lifeline systems; new structural designs technologies of various plant structures based on the performance design approach and on the stochastic damage detection methods for deteriorated structures.
Material and structural behavior of concrete and steel; maintenance management of steel and concrete structures: concrete deterioration due to freezing, melting, fatigue and fire; fatigue and rust of steel; earthquake proof structures.
Damage in soil structures by environmental effects; development of countermeasures, including micro-bubbles and water repellant sands against liquefaction; development of pile foundation systems, soil investigation methods and interpretation including a new Swedish weight sounding test; development of ground improvement methods.
Water environment including coastal areas, rivers, urban water supply, sewage works and atmospheric environment in urban areas. Topics are divided into two categories; (1) coastal and atmospheric environment engineering lab. (2) urban water supply and sewage works engineering lab.
Planning Group; National spatial policy and infrastructure planning, policies for mega trends on planning system concerning with infrastructure, comprehensive land use planning system under the approaching era marked by declining population, participation of various stakeholders in the urban and regional planning process, and creation of sustainable areas.
Management Group; Construction management, policies and missions of civil engineers, information and communication technologies applied in civil engineering, asset management of existing infrastructures based on reliability theory, health monitoring of bridges with vibration induced by a moving vehicle, and economic impact from a natural disaster and its recovery process.
