Doosan Construction Designated as New Technology for Seismic Reinforcement Construction Techniques

[Asia Economy Reporter Kim Min-young] Doosan Construction announced on the 8th that the 'Seismic Retrofit Method,' jointly developed with Korea Disaster Prevention Technology, has been newly designated as a new construction technology (No. 945).

This technology was developed to retrofit seismic resistance for existing low- and mid-rise buildings that were not designed for seismic resistance or require reinforcement. By integrating steel frames and structures with the columns of existing buildings, the strength and stiffness are enhanced to withstand small- to medium-scale earthquakes. Additionally, by introducing an 'energy dissipation device' at the center of the upper beam, it secures a composite resistance system capable of responding to large-scale earthquakes.

Previous technologies reinforced the strength and stiffness of structures by fully integrating simple steel frames with the structural frame and beams, enabling resistance to small- to medium-scale earthquakes. However, when large-scale deformation occurred due to major earthquakes, the stability and response capability of the building were relatively low.

In contrast, this new technology is designed as a seismic structure with composite resistance capable of handling both small- to medium-scale and large-scale earthquakes by designing the upper and lower frames separately. In particular, by incorporating the energy dissipation device, it allows capacity adjustment for strength and stiffness reinforcement without separate foundation reinforcement. From a construction perspective, the existing structure and beams can be constructed separately, significantly shortening the construction period.

In addition to this new technology, Doosan Construction has also developed a seismic piping disaster prevention technology focused on safety and the country's first smart worker safety system utilizing IoT, both of which have been designated as new construction technologies.

A Doosan Construction official stated, "Along with the additional development of the smart worker safety system updated with the latest information and communication technology, we plan to further strive to secure technologies in various fields to build not only safe construction sites but also a safe living environment for the public."
