This laboratory conducts research on the development of technology for the improvement of materials and structural performance of concrete and FRP, which are typically utilized as construction materials, as well as their application and utilization in actual structures.

Structural Analysis Lab is mainly conducting research on the life cycle analysis of structures with uncertainty such as various live loads, corrosion and deterioration, and dynamic behavior such as earthquakes and typhoons. Because a structure is exposed to various environments during its life cycle, the load is always changing and the performance of the structure is constantly changing. Therefore, such variability and uncertainty must be taken into account for the life cycle analysis of structures. Furthermore, we are conducting practical research on facility inspection and diagnosis, performance history analysis, repair and reinforcement construction method selection, future cost prediction, and optimal maintenance cost calculation.

In our lab, we are interested in solving challenging problems in engineering and mechanics. Currently, we are focusing on the offshore wind structure and the concrete material fields. In the offshore wind structure field, we research the design and analysis method for the offshore wind support structures. In the concrete material field, we study the development of new concrete materials for structures. Also, we research the chemo-mechanical models of concrete durability and the application of AI techniques.
Recently, we are starting a new research on digitalization of construction standards using semantic web technology.

In this laboratory, advanced and specialized structural analysis and artificial intelligence-based facility maintenance technologies are being studied. In addition to the conventional fixed structures on land, we are actively conducting research on the development of various offshore structures such as floating transportation systems and floating renewable energy facilities. Also, effective estimation of the structural damages and recognition of the structural state change methodologies are being investigated based on artificial intelligence technologies.

In terms of architectural structure, this lab conducts research on building forensic technology that monitors the structure’s condition in early stages, performance based design, and emerging construction technologies such as 3DP and PCM.

In this laboratory, the behavior of the soft ground, the stress history of the sand, and the cementation effect are investigated by the calibration chamber system and field test.

In order to solve the problem of urban population concentration, insufficient residential space, and overcrowded transportation, this laboratory is leadingly conducting research on the development of tunnels and underground spaces. Therefore, it is concentrated on predicting the front surface of tunnel and underground space smart construction, surface subsidence prediction, risk management, and research on soil conditioning and slurry behavior for shield TBMs. In addition, the research on ground freezing and various grouting techniques related to undersea tunnels and large-scale underground space development, and the development of grouting for nuclear waste storage facilities are being carried out.
