Bamboo is a natural biodegradable material used as a strength-bearing material that operates for system works, formwork supporting stands, structural members in low-rise houses, props, framing, bridges, laminated flooring, facades, walls, roofs, and trusses. Over recent years, there has been an increased demand for bamboo, considering sustainable construction practices. Exploring bamboo’s physical and mechanical behaviour is essential to develop innovative construction methods and design guidelines. Therefore, this paper aims to review the studies on bamboo culms’ material properties and physical behaviour, considering the load-bearing capacity and structural adequacy. This study summarises the physical and mechanical properties of a wide array of bamboo species grown worldwide. Mechanical properties such as compressive, tensile, flexural, shear, and bucking strengths are explored, highlighting the key findings in previous experimental works. Results have indicated a significant variability in bamboo’s material and mechanical properties considering the growth conditions, location along a culm, geometric imperfections and environmental conditions. In addition to material and mechanical properties, structural bamboo connections, engineered bamboo products, and preservative treatment of bamboo are also investigated. The construction industry can utilise the summary of the findings of this study to develop design guidelines for sustainable bamboo construction. Overall, this paper presents an overview of structural capability and drawbacks for future research and development using bamboo in modern construction.

“…Otro estudio comparó el comportamiento entre la unión mediante pasadores internos de madera-hormigón armado y bambú-hormigón armado. Ambas muestras tuvieron un comportamiento similar en los modos de fallo y en el desplazamiento (Wang et al, 2020). La falla fue moderada, dado que las probetas mostraron grandes deformaciones plásticas antes de fallar y el hormigón también presentó grietas, lo que indicó el aporte uniforme de los materiales de la unión.…”

Las primeras normas de construcción con bambú se publicaron a inicios del presente siglo, por lo que no pueden considerarse acabadas. Dentro de ellas, las conexiones, por su extrema complejidad, constituyen elementos poco definidos y son un reto para el diseño estructural. Esto, unido a las características físicas del bambú, es decir, su alta variabilidad, presencia de culmos huecos, de sección curva no uniforme en toda su longitud, no perfectamente rectos y de espesor relativamente pequeño, incrementan la dificultad para el cálculo y hace necesario utilizar diseños que logren resistencia y seguridad. Por ello se realizó una revisión integrativa de investigaciones publicadas, basadas en ensayos estructurales con diferentes tipos de estas uniones. El objetivo fue determinar los tipos de conexiones que ofrecen mejor desempeño estructural según los resultados de ensayos, identificar los principales elementos que contribuyen a su fallo y emitir consideraciones de diseño que permitan incrementar su resistencia y durabilidad. La búsqueda bibliográfica abarcó 287 documentos, utilizando pares de palabras clave. Se seleccionaron los 12 artículos originales que mostraron ensayos realizados con dichas conexiones. Los resultados indicaron la necesidad de utilizar conexiones reforzadas, sin perforaciones ni cortes en el culmo, a través del uso de abrazaderas, que permiten diseños flexibles y sencillos. Los estudios publicados a partir de la realización de ensayos en uniones de bambú son escasos, por lo que es imprescindible el desarrollo de investigaciones de este tipo que provean de herramientas prácticas y confiables a los profesionales que trabajan con estos sistemas.

“…They summarized the failure mode of the composite beam and the effect of the layer number and thickness of BFRP plate on the flexural bearing capacity of the composite beam. Wang et al (2020aWang et al ( , 2020b, Wei et al (2021) studied the bending behavior of bamboo beams composed of different connectors and concrete and found that the stiffness of composite beams can be increased by 4.16 times compared with the base beam. Wei et al (2015) proposed that nearsurface mounted steel bars could be used to strengthen glulam bamboo beams.…”

The embedding of steel bars is proposed to enhance the load-bearing performance of bamboo beams. Based on laboratory tests, the bending behavior of bamboo beams reinforced with steel bars or prestressed steel bars was analyzed using finite element software. Comparing the finite element simulation results with those measured in tests, it can be found that the load–displacement curves coincide with each other, and the strain development processes in the mid-span are basically the same. The prediction by the finite element simulation has good accuracy. The embedding of steel bars and prestressed steel bars can effectively improve the ultimate bearing capacity (up to 27.0%), bending stiffness at the serviceability limit state (up to 42.61%), ductility (up to 22.9%), and material utilization efficiency (up to 34.1%) for the bamboo beams. The embedding of steel bars makes the bamboo in the compression zone of the beams develop with higher efficiency, and applying the prestress for steel bars can produce reverse bending deformation and reduce the actual deflection for the reinforced bamboo beam under service load. Under the same reinforcement ratio, the prestress level has a relatively small influence on the ultimate bearing capacity (up to 4.5%) and stiffness (up to 4.5%) of the reinforced beam.
