- Synopsis
- In 2022, the Architectural Institute of Japan revised the AIJ Standard for Structural Design and Construction of Prestressed Concrete Structures (hereinafter, the “PC Standard”), aligning the organization of its provisions with the AIJ Standard for Structural Calculation of Reinforced Concrete Structures (hereinafter, the “RC Standard”), thereby making the design process for prestressed concrete structures easier to understand. In March 2026, the AIJ Guidelines for Design and Construction of Prestressed Reinforced Concrete (Class III PC) Structures and Commentary (hereinafter, the “PRC Guidelines”) were similarly reorganized to follow the same framework, establishing a clearer connection with the PC Standard. This paper outlines the background to the revision and its main changes.
