Abstract

This chapter serves to summarise the state of the art in the process of material characterisation of bamboo for structural purposes. It also seeks to outline the key characteristics a bamboo researcher or engineer would need to identify for this purpose. The morphological and anatomical characteristics of the bamboo culm are briefly presented. Trends observed by researchers in terms of the effects of density, age, and moisture content on strength and stiffness are presented, as well as the variation of these along the bamboo culm. The importance of considering geometrical in characterisation, as well as physical and mechanical properties, are discussed. Testing procedures and standards are presented to the reader and critically appraised. Published values for Guadua Angustifolia are reported for reference. A process of deriving design values from experimentally derived values is discussed. Suggestions for further research are presented.

Abstract

An exploratory study, conducted at Universidad de los Andes in Bogotá, Colombia, on the potential use of glued laminated bamboo guadua (Guadua Angustifolia Kunt) as a structural material is presented in this paper. The influence of the direction of the fiber and the location of the laminae in the mechanical properties is discussed. The compression, tension, shear, and flexural design stresses of glued laminated guadua are compared to those of Andean structural woods (lumber). Additionally, the effect on the mechanical properties of the bond strength of the adhesive at different test temperatures is investigated. Based on the mechanical properties obtained in this research, glued laminated guadua bamboo can be a suitable construction material for structures.
