【Development】'Foundation Connection/Shear Reinforcement Method' that Enables Labor Saving in Design and Construction
Nippon Steel Engineering Co., Ltd. and Okabe Co., Ltd. have jointly developed a new construction method to reinforce column bases in buildings like logistics warehouses. This 'Foundation Connection/Shear Reinforcement Method' solves the issue of insufficient shear strength when using high-strength braces, contributing to labor savings in design and construction without compromising design freedom.

Nippon Steel Engineering Co., Ltd. (President: Yukito Ishiwa, Headquarters: Shinagawa-ku, Tokyo, hereinafter 'our company') is pleased to announce the joint development of a foundation connection and shear reinforcement method (hereinafter 'this method')*1 with Okabe Co., Ltd. (President and CEO: Hirohide Kawase, Headquarters: Sumida-ku, Tokyo).
This method is a shear reinforcement technique for column bases in steel-frame buildings such as logistics warehouses. It addresses the issue of insufficient shear strength*2 at the column base, which can be a problem when using high-strength braces, without compromising the freedom of spatial planning. This method was first applied at 'Mitsui Fudosan Industrial Park Ebina &forest,' a multi-purpose business facility including logistics use, designed and constructed by our company. This eliminated the need for conventional structural wrapped column bases, enabling a structural plan with exposed column bases, which contributed to simplifying the column base structure and reducing design and construction man-hours for the steel structure.
In steel-frame buildings like logistics warehouses, when the design relies on braces to bear shear forces, the column bases where the braces are attached may have insufficient shear strength. On the other hand, arranging braces in a V-shape to reduce the shear force acting on the column base can compromise spatial efficiency and create challenges by restricting the securing of openings and the freedom of internal traffic flow.
To address these issues, we developed this method, which reinforces the shear strength of the column base without affecting the rotational stiffness*3 of the base. This method is primarily installed at the bottom of the brace on exposed column bases where high-strength braces are attached and is connected to the base plate via non-shrink mortar. This allows the method to add only shear force to the column base.
Furthermore, because this method has a structure that bears only shear force, it reduces the complexity of structural analysis and contributes to the efficiency of design work. In terms of construction, the simple component composition is expected to lead to shorter construction periods and reduced man-hours.
Our company will further promote the efficiency of logistics facility design work with the knowledge gained from this method and contribute to the realization of work style reforms and new possibilities in architectural design.
*1 Our company will market it as 'Base Plus Q3,' and Okabe Co., Ltd. as 'Shear Side Plus.'
*2 An index indicating the capacity of a member or structure to resist forces (shear forces) that act in a direction causing sections of an object to slide past one another.
*3 An index indicating how resistant a member or joint is to rotational deformation when subjected to a bending moment.
