Photogrammetric Inspection on Full-Culm Bending Tests of Italian Phyllostachys edulis
摘要
Bamboo holds significant potential to establish itself as a pioneering material in the European construction industry, mainly due to its high ecological sustainability and remarkable mechanical properties. Despite its advantages and the growing acceptance of bamboo as a construction material, significant knowledge gaps remain regarding the mechanical behavior of bamboo under various loading conditions and orientations due to the non-homogenous structure of bamboo culms. Additionally, for successfully integrating bamboo into the European construction sector, it is crucial to study the mechanical characteristics of locally grown bamboo from Europe, which often exhibit slender diameters. This study therefore investigates the bending behavior of European bamboo culms through experimental analysis. Specifically, ten Italian Phyllostachys edulis culms are subjected to full-culm four-point bending tests, capturing deformations by photogrammetric inspections. The experimental setup and the measurement methodologies are described in detail, followed by the execution and analysis of the bending tests. Subsequently, modulus of elasticity is derived for cyclic and non-cyclic loading based on the photogrammetric data. The results of the bending tests are compared with existing research on Phyllostachys edulis culms. In summary, this study contributes to applying bamboo as a building material in Europe by highlighting the potential of using local resources and facilitating knowledge transfer for the European construction industry.
