“…The mechanical properties of the material reinforced with FRP are generally significantly improved [100][101][102]. In order to solve the problem of low bending strength and stiffness of BS, Wu et al [83] studied the CFRP-BS composite beam. It is found that the CFRP sheet effectively improves the bending modulus and static bending strength of the composite beam, and the failure mode is no longer the fracture failure of the bottom fiber, but the bond failure between CFRP and BS.…”

This review summarizes the existing knowledge about the mechanical properties of bamboo scrimber (BS) in literature. According to literature reviews, the strength of BS under different load modes is affected by a series of factors, such as the type of original bamboo, growth position, resin content, treatment method and density. Therefore, different production processes can be adopted according to different requirements, and bamboo scrimbers can also be classified accordingly. In addition, this review summarizes the changes in different factors considered by scholars in the research on the mechanical properties of BS, so that readers can have an overall understanding of the existing research and make more innovative and valuable research on this basis. This review provides and discusses the conclusive observations, the current research gaps and future research directions on the mechanical properties of BS.

To improve the bending performance of long-span bamboo scrimber beams, a new method of prepressing-cold pressing-hot forming was used to produce steel-reinforced bamboo scrimber composite beams. For steel-RBSC beams, four-point bending experiments were performed to study the failure mode, bending performance, load-displacement relationships, and strain history curves of composite beams. Based on cohesive zone model theory, finite element models of steel-RBSC beams were established and the bonding stress of the adhesive layer in steel-RBSC beams revealed. The results indicated that the failure mode of composite beams was fracture failure of the bamboo scrimber at the bottom between the loading rollers. Steel reinforcement had a significant effect on the strength and stiffness of bamboo scrimber beams. The maximum static stiffness of composite beams was increased by 70.15%, compared with that of bamboo scrimber beams. The load-displacement curves, mechanical properties, and section strains predicted by finite element models were consistent with the test results, verifying that these finite element models were correct. The main influence factors for the peeling of the adhesive layer were normal stress, shear stress, and mixed stress in the areas of pure bending section, bending-shear section, and loading roll area, respectively.

“…With the invention of bamboo composites, such as laminated bamboo lumber [82][83][84][85][86][87], glubam [88][89][90][91][92], parallel strand bamboo [93][94][95][96][97], and their combinations with AFRP, CFRP [98,99], and other materials, the possibility of using bamboo as reinforcement for concrete is significantly expanding. Multiple studies have been done on new types of bamboo-based and concrete composites, such as engineered bamboo-concrete sandwich panels, bamboo particle concrete, bamboo fibre concrete, bamboo tube grid concrete panels, etc., showing wide possibilities of utilization of bamboo variations in composites with concrete [100,101].…”

In light of the increasing demand for sustainable building materials, the effectiveness of bamboo utilization in various fields has become the object of scientists' close attention. The increased interest in bamboo is explained by its sustainable characteristics, which make it the most preferred material for environmentally friendly and costeffective construction compared to conventional ones. Applicability of bamboo is vast and diverse: from decoration and furniture to structural members and reinforcement. Due to the low price, rich resources, and high elasticity, bamboo culms have also been used as an alternative to steel reinforcement in concrete structures. Extensive research has been done to assess feasibility of bamboo reinforcement in structural elements made of concrete. This article discusses the mechanical properties of three types of structural bamboo reinforced concrete (BRC) beams. Existing original papers on the mechanical behaviour of structural BRC members were studied, and the fundamental properties including typical failure modes, reasons of failure, load-displacement relationships, and influencing factors were discussed and described. Observations and conclusions of the review will contribute to deep understanding of structural feasibility of BRC beams and serve as a base for future research.
