- Long-span Composite Beam
- We conduct research on the development of composite beam technology, which maximizes structural performance by combining steel for concrete structures with shear connectors. This technology can be applied to structures with a span length of 24 meters, and is currently being utilized in the field in high-tech projects.

- Structural Analysis and Design for Super High-rise Buildings
- The objective of structural analysis and design technology is to ensure the highest level of quality by examining the economy, stability, usability, livability, and constructability of super high-rise buildings during the design stage to minimize potential problems during the construction phase. To achieve this, we research, develop, and apply related core technologies in the field.

- Construction Stage Analysis Technology
- Unlike completed buildings, structures under construction require separate safety and building deformation evaluations based on the construction method and temporary structures used. To ensure construction safety and the best building quality, we predict structural deformation according to the construction stage, and monitor the walls and columns in real time during on-site construction.

- Analysis and Design of Large Space Structures / Erection Engineering
- The design and construction process of large space structures can be summarized as analysis, design, fabrication, and erection monitoring. Based on Space Frame analysis, membrane shape and member optimization, nonlinear analysis, and construction stage-specific analysis technologies, we conduct research and development and provide on-site support for large space structures composed of Truss, Space Frame, Cable, and Membrane. We are applying advanced analysis and optimization design technologies, such as geometry and material nonlinearity analysis, essential for the optimal design of large space dome structures with various support conditions and special shape-resistant structures, as well as Erection Engineering technologies in consideration of the construction stage.
