“…From the results presented in Table 4, it is possible to see that elements extracted from the bottom of Guadua culms have a higher volumetric contraction index than elements extracted from the middle and top regions (for moisture content below the saturation point of the fibers). Similar results were obtained by Gutierrez et.al [26], and may be associated with the graded functionality of the material [1], [27], [28]. The higher content of parenchymal tissue present in the base of the culms promotes a rapid absorption of water in the material, affecting the performance of material when it is subjected to From the results shown in Figs.…”

Introduction: Due to its earthquake behavior, the use of bamboo for structural purposes has increased in the latest decades, mainly in South American countries, in which, their employment, has been standardized in the design bases. However, for the efficient use of bamboo as a construction material, it is necessary to consider that being a natural material, volumetric variations can occur, especially when the material is subjected to changes in moisture between the saturation point of the fibers and the equilibrium moisture. Objectives: The objective of this paper is to evaluate the influence of the moisture content on the mechanical properties of elements extracted from the bottom, middle, and top of bamboo culms. Methodology: For the study, research is carried out with a quantitative approach. The experimental characterization was focused on the determination of compression, bending, and shear strength, according to the recommendations of the Colombian Technical Standards. Results: Results allow verifying that bamboo elements are susceptible to vary their strength and stiffness depending on the equilibrium moisture of the region to be considered in the structural design. Conclusions: The influence of the moisture content on the mechanical properties of elements extracted from the bottom, middle, and top of bamboo culms was evaluated. The experimental characterization was focused on the determination of compression, bending, and shear strength. From the results, it is possible to verify that an increase in the moisture content reduces the mechanical strength of the material. The decrease in the values of maximum stress is more significant for moisture values between 12 % and the saturation point of the fibers and is accompanied by important dimensional changes that impair the mechanical performance of the material. The results show that above the point of saturation of the fibers the mechanical behavior of the culms is not modified.

“…After that fall, bamboo recovers some of the strength, and the normalised strength tends to rise for temperatures between 100°C and 150°C. At that temperature range, water evaporates, and higher strength can be achieved due to moisture evaporation, as reported in various studies (GutierrezGonzalez, Bonilla Santos, Cruz Amado, & Quintero Aranzalez, 2018;Xu, Harries, Li, Liu, & Gottron, 2014), however, further research must be conducted to fully understand the effects of the moisture content and moisture migration on the reduction of mechanical strength at elevated temperature. When temperatures exceed 150°C, the strength falls again, and this can be related to the onset of pyrolysis around that temperature.…”

The remarkable high strength-to-weight ratio of bamboo and the recent innovations and development of laminated bamboo products has enabled the potential for new larger and taller structural bamboo applications. However, there is little understanding of the behaviour and performance of bamboo structures during and after a fire. To date, bamboo has been used widely in low-rise constructions I am infinitely grateful with my amazing friends from the coffee, and beer club, Angela, Aaron, Juan Patricio, Ian, Luis, Sergio, Jaime, Andrea, Abed. I would not have completed this journey without your support and positive energy. They became like my family in Brisbane, and when I had to push uphill, they were always there to struggle with me, to motivate me, to make me grow, and make me laugh in the happiest and most difficult moments. My love and respect go to the UQ Fire family for their support, enlightening conversations, and diligent work.

El sector de la construcción es un pilar fundamental para la economía y el desarrollo del país. En años recientes, este ha tenido un crecimiento a gran escala, pero también ha sido uno de los sectores donde se generan más residuos sólidos, tanto ordinarios como de construcción y demolición, los cuales son dispuestos en botaderos a cielo abierto o en escombreras, con una gestión deficiente, provocando diversos problemas a la comunidad cercana y al medio ambiente. El aprovechamiento de residuos sólidos aplicados a proyectos constructivos ha sido considerado como una alternativa de sostenibilidad ambiental; por lo anterior, en esta investigación se implementaron residuos de construcción y demolición, botellas de tereftalato de polietileno (PET, por sus siglas en inglés), tierra, guadua, residuos madereros, restos de alambre y envolturas plásticas en la construcción de galpones como alternativa de mejora en comunidades rurales afectadas por la violencia en Antioquia, específicamente en el corregimiento El Prodigio del municipio de San Luis. Como resultados se determinó que la implementación de materiales alternativos en la construcción de galpones permitió la integración social y la reducción del deterioro ambiental debido al uso de 1864 kg de materias primas residuales consideradas para la comunidad como desechos, y 279 kg de materiales no residuales, donde un elemento natural como la guadua ocupó el mayor valor porcentual con 95 %, y el 5 % restante, correspondiente a materiales propios del sector de la construcción. Por lo tanto, la aplicación de la sostenibilidad dirigida al campo avícola promueve el uso de materiales alternativos en lugares donde es necesario su aprovechamiento como mejora ambiental y social; es por lo anterior que en esta investigación surge como objetivo general minimizar los residuos plásticos presentes en la parte urbana y rural de la zona de estudio.
