Engineers in Japan develop earthquake-resistant “CLT checkered block wall”

earthquake resistant solution

A team of engineers at Japan-based kozo keikaku kunkyusho has developed an “earthquake-resistant CLT checkered block wall”. The system simply consisted of cross-laminated wood panels organized in a checkered pattern, steel plates, and drift pins. The solution considers seismic safety, daylighting, passive ventilation, and beautiful design.

kengo kuma & Associates is currently designing the Himawari Kindergarten, or “children’s garden”. The architects will collaborate with kozo keikaku kunkyusho and use this earthquake-resistant solution.

By using the earthquake-resistant CLT checkered block wall, kozo keikaku kenkyusho indicates that it is possible to secure lighting and ventilation – which was the problem of the way the panel was built into the wall structure – and to achieve a CLT building with thoughtful design and operability. Along with the modular construction strategy, the team hopes to develop its application as a seismic component for other structures including those built of steel and reinforced concrete. Stay tuned for more information as the architects at kengo kuma & Associates develop Himawari Kindergarten.
