ABSTRACT

Redirecting the actual construction industry, which is one of the major sources of global pollution, is relevant to achieve green innovation efficiency. Researching on the potentials of wood species can lead to propose alternatives that allow reducing/reinventing conventional building materials and systems. This investigation aims to determine, evaluate and analyze the biomechanical/structural properties and performances of lightweight sandwich-like composite biopanels made of bamboo, melina and balsa. A total of 92 samples were experimentally tested under compression, bending, shear, tension, density, moisture content, glue and ply-delamination. The experimental data were validated and compensated through 82 finite element analyses. The acquired results were compared with equivalent sections of conventional materials in terms of strength, rigidity, structural behavior and mechanical efficiency. E.g. the results show the biopanels are up to two and three times more mechanically resistant than solid wall bricks and concrete block walls, respectively; and, up to nine times higher in terms of mechanical efficiency than steel. The results from the biomechanical analyses confirm the practical utilization of the wall biopanels into nonconventional building projects even as structural elements; most important, the implementation of the proposed wall biopanels into actual building systems would significantly reduce fatalities and destroyed dwellings during seismic and windy events due to its remarkable flexibility, strength and ductility.

创新的三明治状复合生物板–面​​向非常规建筑系统中结构应用的新型建筑生物材料概念

抽象的

改变实际建筑业是全球污染的主要来源之一,这与实现绿色创新效率息息相关。对木材物种潜力的研究可以导致提出替代方案,以减少/重新发明传统的建筑材料和系统。这项调查旨在确定,评估和分析由竹子,黑麦草和轻木制成的轻质三明治状复合生物面板的生物力学/结构特性和性能。总共92个样品在压缩,弯曲,剪切,拉伸,密度,含水量,胶水和层离下进行了实验测试。通过82个有限元分析对实验数据进行了验证和补偿。将获得的结果与常规材料的等效截面的强度进行比较,刚性,结构性能和机械效率。例如,结果显示,生物面板的机械强度分别比实心砖墙和混凝土砌块墙高两倍和三倍;并且在机械效率方面比钢高9倍。生物力学分析的结果证实了壁板生物面板在非常规建筑项目中的实际利用,甚至可以作为结构要素使用。最重要的是,由于拟议的墙体生物面板具有显着的柔韧性,强度和延展性,因此在实际的建筑系统中实施墙体生物面板将显着减少地震和刮风事件期间的死亡人数和被破坏的房屋。结果表明,生物面板的机械强度分别比实心砖墙和混凝土砌块墙高两倍和三倍。并且在机械效率方面比钢高9倍。生物力学分析的结果证实了壁板生物面板在非常规建筑项目中的实际利用,甚至作为结构元素。最重要的是,由于拟议的墙体生物面板具有显着的柔韧性,强度和延展性,因此在实际的建筑系统中实施墙体生物面板将显着减少地震和刮风事件期间的死亡人数和被破坏的房屋。结果表明,生物面板的机械强度分别比实心砖墙和混凝土砌块墙高两倍和三倍。并且在机械效率方面比钢高9倍。生物力学分析的结果证实了壁板生物面板在非常规建筑项目中的实际利用,甚至可以作为结构要素使用。最重要的是,由于拟议的墙体生物面板具有显着的柔韧性,强度和延展性,因此在实际的建筑系统中实施墙体生物面板将显着减少地震和刮风事件期间的死亡人数和被破坏的房屋。生物力学分析的结果证实了壁板生物面板在非常规建筑项目中的实际利用,甚至可以作为结构要素使用。最重要的是,由于拟议的墙体生物面板具有显着的柔韧性,强度和延展性,因此在实际的建筑系统中实施墙体生物面板将显着减少地震和刮风事件期间的死亡人数和被破坏的房屋。生物力学分析的结果证实了壁板生物面板在非常规建筑项目中的实际利用,甚至可以作为结构要素使用。最重要的是,由于拟议的墙体生物面板具有显着的柔韧性,强度和延展性,因此在实际的建筑系统中实施墙体生物面板将显着减少地震和刮风事件期间的死亡人数和被破坏的房屋。
