Structures Management Engineering

The primary task of our laboratory is to develop the advanced design method, the prolonging method and the environmental-load-reduction method of infrastructures by means of composite structures combining various materials including Concrete, Steel, Fiber Reinforced Polymers (FRP) and other advanced materials. Furthermore, our research activities also include:

Research Topics

The recent study can be specified primarily by the performance of steel structures, steel-concrete composite structures and FRP structures secure in the earthquake, while considering its durability and environmental-load-reduction. The study is also extended to develop a health monitoring system and a rehabilitation methodology of structures.

Research Topics

Development of monitoring systems using advanced sensors such as optical fibers

Health monitoring is indispensable in maintaining structures or controlling natural disasters. Our research focuses on the development of long-term monitoring systems for various structures on the basis of advanced sensing technologies such as fiber optic sensors.

Recently, fiber optic sensors have been applied to measure temperature, strain, displacement, acceleration and other structural responses based on various measurement principles. Among the fiber optic sensors, the Fiber Bragg Grating (FBG) sensor is further developed and included into the remote monitoring system as a solution that contributes to the practical application. Ground deformation measurement in severe construction environments such as open cut excavation of tunnels is one example.

Development of Sulfur-Slag Concrete

Sulfur is a sub-production of oil refinery. Furnace blast slag and fly ash are also sub-production of steel manufacture and thermal power generation. Using these sub-products, polymer concretes hardened by sulfur solidification, have been proposed in the past researches. Sulfur-Slug Concrete (SSC) is one of the polymer concretes but has high compression strength as well as ductility owing to the olefin additive. Various advantages have been found in SSC, such as a high strength of around 80MPa, high ductility, high durability against acid, etc.

Researches on health evaluation approaches and maintenance management techniques

Maintenance management of the concrete structures is requisite for the sustainability and feasibility of social development. Exploration and development of health evaluation system for the deteriorated and/or damaged concrete structures is the main purpose of this topic. Based on the requirement of retrofit or upgrade in terms of the durability and load carrying capacity after evaluation, the repair and/or strengthening techniques can be proposed. A systematic selection methodology including the selection of the repair and strengthening materials and the related construction techniques is being proposed and examined depending on the efficiencies of these materials and techniques.
