Precast concrete is a key technology in the modern construction industry, boasting structural efficiency, construction speed, and quality consistency. It is also attracting attention as an alternative for sustainable construction, including addressing climate change and reducing carbon emissions.
Accordingly, the new National Construction Standards KDS 41 20 10 Precast Concrete Structure Design Standards for Buildings were established in 2024 to complement the limitations of the existing 1992 standards and reflect factors such as floor limit restrictions and expanded earthquake-resistant systems.
The new standard provides specific step-by-step design methods for materials, manufacturing, assembly, and completion, and includes the latest design contents such as structural stability design and structural diaphragm design.
This commentary is designed to help practitioners accurately apply the standards to their field based on the background, technical data, and experimental results of the standards, and is intended to provide practical assistance in the design and construction of precast concrete buildings.
