Summary: This study investigates the bending failure mechanism of bamboo scrimber (BS) and provides insights for its rational design and safe application in engineering. The study reveals that the macroscopic and microscopic properties of BS exhibit typical brittle failure, which is influenced by multiple stress factors. The elastic modulus of BS is greatly increased due to the concentration of sclerenchymatous cells. Important factors contributing to the brittle failure mechanism include compression of energy absorption tissues, resin filling in cavities, and decomposition of hemicellulose.

Summary: Bamboo scrimber composite (BSC) is an emerging engineering material with advantages of structural design, water resistance, and fire resistance. This study investigates the rebonding performance of BSC, which depends on surface properties influenced by density and resin content. The study reveals that increasing density and resin content improves the rebonding performance by modifying the porous structure, reducing surface roughness, and enhancing surface wettability.

Summary: The study found that the compressive strength and elastic modulus of bamboo scrimber were greater in the longitudinal direction compared to the radial and tangential directions, with more ductile fracture observed in longitudinal compression specimens. The failure modes of bamboo scrimber also varied in different directions, which was attributed to the location of maximum strain.

Summary: This study investigated the long-term mechanical properties of bamboo scrimber (BS), including the duration of load (DOL) and creep effects. It found that BS had a more severe DOL effect compared to other structural wooden materials, but a smaller relative creep strain. The study also provided time-dependent constitutive models for predicting the DOL factor and creep strain of BS under different load durations, which is beneficial for its long-term safe application as a new structural material.

Summary: This paper presents experimental and theoretical investigations on the behavior of short bamboo scrimber box columns under compression. The experimental results show that when the width-to-thickness ratio of plates is less than or equal to 10, the box columns exhibit compression failure, reaching the ultimate compressive strength of bamboo scrimber. However, when the ratio exceeds 11, local buckling of bamboo scrimber plates is observed instead of compression failure, and the ultimate compressive stress decreases with increasing width-to-thickness ratio. Theoretical analyses considering the nonlinear stress-strain relationship provide reasonably good estimations of the local buckling stress for columns with a width-to-thickness ratio greater than 10.

Summary: This study clarifies the hygric properties of laminated bamboo (LB) and bamboo scrimber (BS), two emerging bamboo products for building materials. The study reveals that LB and BS have lower moisture storage and transport capacities compared to reference timber. Additionally, the critical relative humidity for mold growth on LB and BS is lower than the internationally used value for timber, making bamboo more susceptible to moisture damage.

Summary: Shear failure parallel to grain is a common failure mode for bamboo scrimber under flexural loading. The bamboo scrimber beams were reinforced with bamboo pins to address this issue. Four-point bending tests were carried out to analyze the failure mechanism, ultimate bearing capacity, load-deflection curves, load-strain relationship, strain distribution, and interlayer slip law of the bamboo scrimber beams. It was found that the bamboo pins effectively resisted shear failure and increased the ultimate bearing capacity of the beams.

Summary: This study investigates the dowel-bearing behavior of bolted joints on bamboo scrimber and proposes estimation formulas based on experimental analysis. The results show that bolt diameter, sample thickness, and loading direction have an influence on the dowel-bearing behavior. Additionally, the failure mechanisms differ between samples loaded in parallel and perpendicular to the grain direction.

Summary: Thermal treatment plays an important role in the modification of bamboo, improving its physical, mechanical, and fire performance, making it suitable for use as structural engineering materials. The HL group of bamboo scrimber processed with superheated steam at a temperature of 200 degrees C exhibits exceptional dimensional stability and fire resistance, but slightly lower mechanical properties. Thermal treatment leads to changes in chemical components and microstructures of bamboo, affecting its performance.

Summary: A new method of prepressing-cold pressing-hot forming was used to produce steel-reinforced bamboo scrimber composite beams to improve their bending performance. Four-point bending experiments were conducted on the steel-RBSC beams to study their failure mode, bending performance, load-displacement relationships, and strain history curves. Finite element models of the steel-RBSC beams were established based on cohesive zone model theory, revealing the bonding stress of the adhesive layer. The results showed that the failure mode of the composite beams was fracture failure of the bamboo scrimber at the bottom between the loading rollers.

Summary: This study investigates the transverse compression behavior of Moso bamboo and its relationship with density, and provides microscopic observations of cellular structure changes during transverse loading. Bamboo exhibits higher compression modulus and yield strength compared to softwood of the same density. The matrix of bamboo acts like a closed cell foam during transverse compression, with significant density variation among specimens, and plays a crucial role in its overall density, behavior, and compression modulus. Furthermore, tissue density and the natural fiber reinforced composite structure of bamboo also influence its behavior and compression modulus. A refined model is proposed to capture the nonlinear stress-strain behavior of bamboo considering these characteristics, and it accurately predicts transverse compression behavior and magnitude within the range of Moso bamboo densities.
