“…However, not all studies raised indicate the same positive correlation [16]. The experiments done on laminated Guadua angustifolia bamboo indicate an inverse correlation between the dowel diameter and ultimate dowel bearing strength [33].…”

“…This trend is seen regardless of the associated node placement along the specimen, indicating that the two (2) variables are independent of each other and can be analyzed separately. The exact correlation of the dowel diameter towards the ultimate dowel bearing strength of the specimen is influenced by various factors as per several studies et al [16].…”

“…Dowel bearing strength is the property of connection members that imparts resistance to the embedding of a dowel. To provide strength and stability to bamboo structures, the dowel bearing strength needs to be carefully considered [16]. It is critical to consider the bamboo culm's bearing capacity while employing a dowel-type fastener in bamboo connections.…”

“…According to [19], the properties of the bamboo culm are enough to estimate the mechanical potential of bamboo in bamboo-based composites. Various studies showed experimental results utilizing different variables, such as bolt diameter [16], the distance of fastener to node [20], moisture content [21], temperature, and more, that would affect the dowel-bearing strength of bamboo, such as a study that exhibited an increase in the ultimate failure stress as end distances of joints increase while the increase of bolt diameter would result in the decrease of the ultimate bearing stress of bamboo under a bolt [22]. While some studies focused on the variability of factors, others would have speciesspecific studies, just like how wood species for joints also play a crucial role in determining its strength [23].…”

This study addresses the critical issue of dowel-bearing strength in Bambusa blumeana, a key sus-tainable construction material crucial for climate change mitigation. Given the lack of bamboo connection standards, the research focuses on determining the dowel-bearing strength of Bambusa blumeana, emphasizing factors such as dowel diameter, node placements, and the physical prop-erties of bamboo. A predictive equation is derived, enhancing the practicality of bamboo in struc-tural design. The results underscore a notable correlation between dowel diameter and character-istic strength, with implications for engineering practices. Node placements significantly affect dowel-bearing capacity, while bamboo's physical attributes, including thickness, culm diameter, and moisture content, exhibit modest correlations with strength. The derived equation aims to assist in structural design, mitigating splitting and bearing failures in bamboo structures. This research establishes a foundation for optimizing the use of Bambusa blumeana in sustainable construction, advancing the understanding of its dowel-bearing strength for improved sustainability and resili-ence in the construction industry. Future research suggestions include exploring bamboo-mortar composites, additional node placements, and employing more comprehensive empirical equations and curve-fitting techniques. The study advocates for further investigations with more diverse and larger bamboo samples to bolster robustness. Additionally, delving into bamboo ductility may offer valuable insights.

A theoretical analysis of upward deflection and midspan deflection of prestressed bamboo-steel composite beams is presented in this study. The deflection analysis considers the influences of interface slippage and shear deformation. Furthermore, the calculation model for flexural capacity is proposed considering the two stages of loading. The theoretical results are verified with 8 specimens considering different prestressed load levels, load schemes, and prestress schemes. The results indicate that the proposed theoretical analysis provides a feasible prediction of the deflection and bearing capacity of bamboo-steel composite beams. For deflection analysis, the method considering the slippage and shear deformation provides better accuracy. The theoretical method for bearing capacity matches well with the test results, and the relative errors in the serviceability limit state and ultimate limit state are 4.95% and 5.85%, respectively, which meet the accuracy requirements of the engineered application.
