This study proposes a new solution to these challenges through the use of a formwork system called Auxetic Bending-Active Formwork (ABAF). ABAF enables the formation of freeform surfaces with both positive and negative Gaussian curvature by elastically deforming flat grid structures on-site. This method allows the formwork to be shipped flat and reshaped on-site, making it reusable and more efficient for construction.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>*This research was supported by JSPS KAKENHI 24K01031.\u00a0<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Published Paper :&nbsp;<a href=\"https:\/\/papers.cumincad.org\/data\/works\/att\/caadria2025_47.pdf\" title=\"\">[Download from here]<\/a><br>Title\uff1aAuxetic Bending-Active Formwork System for Free-Form Continuum Shells<br>Authors : Nakayama K., Awaji H., Sakai Y., Yoshikawa R., Hayashi S., Gondo T., Kimura T.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"600\" src=\"https:\/\/www.sonycsl.co.jp\/kyoto\/wp-content\/uploads\/2025\/08\/image-2.png\" alt=\"\" class=\"wp-image-1543\" srcset=\"https:\/\/www.sonycsl.co.jp\/kyoto\/wp-content\/uploads\/2025\/08\/image-2.png 800w, https:\/\/www.sonycsl.co.jp\/kyoto\/wp-content\/uploads\/2025\/08\/image-2-300x225.png 300w, https:\/\/www.sonycsl.co.jp\/kyoto\/wp-content\/uploads\/2025\/08\/image-2-768x576.png 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"600\" src=\"https:\/\/www.sonycsl.co.jp\/kyoto\/wp-content\/uploads\/2025\/08\/image-3.png\" alt=\"\" class=\"wp-image-1544\" srcset=\"https:\/\/www.sonycsl.co.jp\/kyoto\/wp-content\/uploads\/2025\/08\/image-3.png 800w, https:\/\/www.sonycsl.co.jp\/kyoto\/wp-content\/uploads\/2025\/08\/image-3-300x225.png 300w, https:\/\/www.sonycsl.co.jp\/kyoto\/wp-content\/uploads\/2025\/08\/image-3-768x576.png 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/figure>\n","protected":false},"template":"","class_list":["post-1542","project","type-project","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 5.0.0.1 - aioseo.com -->\n\t<meta name=\"description\" content=\"Member : Yusuke Sakai Designing complex freeform surfaces remains challenging, particularly in fabricating, transporting, and reusing formwork.
