LITERATURE REVIEW

2.1 General

This chapter provides a literature review spanning the range of the complex biology of bamboo for understanding to prior research conducted on mechanical behavior and different applications of bamboo.

2.2 Design Provisions
Technical documents describe the benefits, uses, and equations for structural materials. A structural codebook for bamboo does not exist, but the first manual for bamboo design was published in 2000 with the ICC‟s technical document titled Acceptance Criteria for Structural Bamboo, and the second in 2001 with the ISO‟s document Bamboo Structural Design (ISO 22156). The ICC‟s document defines codes and references to use during structural bamboo design and procedures for testing. The ISO document, referred to as ISO 22156, was created to centralize the suggestions of researchers. ISO 22156 is not an international standard, but a step in the recognition of bamboo by other agencies as a structural material and creation of a codebook for design. ISO 22156 has suggestions for design and drawing details to provide adequate guidance essential for proper bamboo structural design. ISO 22156 is summarized to increase understanding of requirements for designing bamboo structures. Traditional knowledge can provide adequate design of bamboo structures, but structural engineering occurs when the engineer verifies the loads on a building and executes a safe, affordable, and sustainable design. Generally, a material has a codebook governing the structural design, which has information regarding equations, detail guidelines, and construction practices. Bamboo has a manual of guidelines, ISO 22156, and empirical design criteria to accommodate quality design practice but requires the dev...

This description of ISO 22156 refers to key points for design and construction of structural bamboo. The document is purely descriptive, not prescriptive in the guidelines and does not provide values or equations for the design process.
2.32 General Properties and Failures
General properties and failures of bamboo in design include the inherent variation of culms and buckling. Culm variation contributes to the difficulty of designing bamboo structures and obtaining accurate quantitative data. Bamboo is weak because of variation in the cross-section, which can substantially impact the bending and axial stiffness of the culm (Arce-Villalobos, 1993). Buckling occurs in bamboo culms because of bamboo culm’s slenderness and curvature (Yu et al., 2003). Both qualities are avoidable through quality control and design checks throughout the design and construction process.
