This is an Open Access article distributed under the terms of the Creative Commons Attribution License 4.0 (http://creativecommons.org/licenses/by/4.0/). abstract: Bamboo is one of the most promising sustainable construction materials due to the large endemic natural reserves prevalent in the Southern Hemisphere. However, industrialised materials, such as concrete, steel and aluminium have overshadowed the application of natural bamboo culms, due to the high-quality assurance achieved over decades refining the production processes of structural elements manufactured from the former. As a result, the physical, geometric and mechanical properties of these industrialised structural elements are quantifiable, predictable and in agreement with international standards. This research presents the details of a digital workflow to quantify the inherent geometric variability of bamboo culms as part of a new quality assurance process for this natural structural element. This workflow relies on the use of a mid-range, commercially available structured-light 3D scanner to accurately capture a point cloud of the bamboo geometry and generate a corresponding polygon mesh. Digital models of three different bamboo species were validated through comparison with key physical measurements finding that the adoption of these digital models can significantly improve the accuracy and efficiency of manual methods due to the complex irregularities found in bamboo culms. This work demonstrates the benefits of adopting a non-destructive, reverse-engineering approach to quantify the geometric properties of bamboo compared to traditional tools and methods. Overall, this research shows the potential of digital technologies to support the adoption of this natural material allowing for the re-assessment of design workflows and providing an opportunity for bamboo to compete with industrialised materials. date: 2019 date_type: published publisher: EDP Sciences official_url: https://doi.org/10.1051/matecconf/201927501024 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1661980 doi: 10.1051/matecconf/201927501024 lyricists_name: Lorenzo, Rodolfo lyricists_id: RLORE19 actors_name: Flynn, Bernadette actors_id: BFFLY94 actors_role: owner full_text_status: public series: MATEC Web of Conferences publication: 1ST INTERNATIONAL CONFERENCE ON ADVANCES IN CIVIL ENGINEERING AND MATERIALS (ACEM1) AND 1ST WORLD SYMPOSIUM ON SUSTAINABLE BIO-COMPOSITE MATERIALS AND STRUCTURES (SBMS1) volume: 275 pagerange: 1-11 pages: 11 event_title: 1st International Conference on Advances in Civil Engineering and Materials (ACEM1) and 1st World Symposium on Sustainable Bio-composite Materials and Structures (SBMS1) (ACEM2018 and SBMS1) event_location: Nanjing Forestry Univ, Nanjing, PEOPLES R CHINA event_dates: 09 November 2018 - 11 November 2018 institution: 1st International Conference on Advances in Civil Engineering and Materials (ACEM) / 1st World Symposium on Sustainable Bio-Composite Materials and Structures (SBMS) issn: 2261-236X book_title: Proceedings of the 1st International Conference on Advances in Civil Engineering and Materials (ACEM1) and 1st World Symposium on Sustainable Bio-composite Materials and Structures (SBMS1) (ACEM2018 and SBMS1) editors_name: Li, H editors_name: Ashraf, M editors_name: Corbi, O editors_name: Yang, P editors_name: Corbi, I editors_name: Wang, L citation: Lorenzo, R; Mimendi, L; (2019) Digital workflow for the accurate computation of the geometric properties of bamboo culms for structural applications.
