"Wall-type × thin-walled single reinforcement" high durability low-cost smart wall construction method
Wall thickness 150mm, wall-type reinforced concrete construction.
The Smart Wall construction method is... With numerous massive earthquakes of seismic intensity 7 observed across the country, it has become difficult to balance "cost" and "earthquake resistance" amid rising construction costs, causing significant challenges for both builders and operators. The Smart Wall construction method is a wall-type reinforced concrete structure that is highly earthquake-resistant and durable, yet low-cost, capable of withstanding earthquakes of seismic intensity 7, similar to the Great Hanshin-Awaji Earthquake.

basic information
In the Great Hanshin-Awaji Earthquake, while there were buildings that were severely damaged or collapsed in areas with a seismic intensity of 7, WRC structures only experienced minor damage, with just two buildings showing cracks of 5mm in width at the openings, rather than any significant destruction or collapse. It has become somewhat common knowledge among us structural designers that this structural form has extremely high seismic resistance based on past major earthquakes. WRC structures also offer spacious interiors without columns or beams intruding into living spaces, along with high durability, fire resistance, airtightness, sound insulation, and low cost as advantages. Sakura Structures has developed the 'Smart Wall Method,' which maintains these advantages while further pursuing cost efficiency, constructability, and durability. The features of the 'Smart Wall Method' include a wall thickness of 150mm and single reinforcement, achieving low costs. By adopting special concrete and external insulation methods, it also takes crack prevention into consideration. A full-scale experimental building with four stories, a wall thickness of 150mm, and single reinforcement has already been completed next to our headquarters in Sapporo, and we are currently observing its progress.
