AIJ Standard for Structural Calculation of Reinforced Concrete Structures was revised in eight and a half year from the last edition. The following three points were revised mainly: bond, foundations, and shear walls. In the provision of bond, verification of safety (ultimate strength) was reviewed. In particular, new knowledge of bond around continuous reinforcement and cut-off bars have been reflected, and calculating method have been simplified. In calculation of shear in foundations, the arch mechanism can now be taken into consideration specifically for foundation slabs that meet special regulations concerning shear reinforcement and other conditions. In the commentary on shear walls, more explanations for beams confining wall, the reduction factor related to opening height, and so on, have been added.
