Overcoming challenges in bamboo connections: A review of mechanical properties and structural considerations

2025-09-22

AI Summary

Limited understanding of connection performance constrains the engineering application of bamboo structures. This study addresses this gap through a systematic literature review and comparative analysis to clarify how anatomical, geometric, and mechanical properties of bamboo influence connection behavior, while critically evaluating the limitations of existing classification systems (e.g., Janssen’s and Widyowijatnoko’s). Methodologically, it proposes an integrated connection design framework that jointly considers structural load-transfer requirements and constructability—explicitly defining force-transfer mechanisms, critical performance parameters, and buildability criteria. The contribution includes a practical connection selection guide and a standardization pathway tailored for engineering implementation. This work fills a critical research void in systematic connection design for bamboo structures and advances the scalable deployment of sustainable bamboo architecture.

Abstract

Over the past decades, bamboo has increasingly gained attention as a sustainable construction material, through its rapid growth, naturally optimized shape, high mechanical properties, and significant environmental benefits. However, despite these advantages, the use of bamboo in its natural form for structural applications remains limited, partly due to insufficient knowledge of connection behavior, which is crucial for ensuring the long-term reliability and performance of bamboo structures. This article provides a comprehensive review of the key factors to consider in the design of structural bamboo connections and discusses the existing connection classification methods used as guidelines by designers. By synthesizing findings from the literature, our research aims to identify the key parameters interacting with the connection design process, focusing on the anatomical, geometric, and mechanical properties of bamboo, the mechanical requirements of the structure design, and the building methods. A critical analysis of Janssen's classification of bamboo connections, based on force transfer modes and later refined by Widyowijatnoko, is presented. Finally, we discuss the identified research gaps and emphasize the need for integrated design approaches supported by guidelines to support the broader adoption of bamboo in construction.
