Confined Bamboo Guadua LaminatE – CBGL

A. Cruz, C. Takeuchi

Abstract. The constructive technique called Confined Bamboo Guadua Laminate (CBGL) is an improvement of the mechanical properties of wood with low specifications, by means of the reinforcement of laminates of Bamboo Guadua angustifolia Kunth, in a composite section. The CBGL is a composite section of pieces of softwood that confine laminates of guadua. Thus, low mechanical specification wood can be used for structural constructions with the CBGL technique. Compression parallel fiber tests were carried out for wood, bamboo, Guadua angustifolia Kunth laminates and for the composite section of wood and bamboo guadua laminates, to demonstrate the advantages of the CBGL construction technique. The density was determined for each material. The elasticity modulus (E), the maximum stress (σmáx) and the proportionality limit stress (σLP) were obtained with the results of stress–strain graph tests. The experimental data of the composite section were compared with theoretical and numerical data analysis, demonstrating the efficiency of the CBGL constructive technique. Wood from reforestation and fast-growing processes, with the CBGL construction technique, can accomplish structural requirements and become an alternative to hardwood with high mechanical resistance, but longer growing time. In this way, not only the selection processes of structural elements for constructions in wood are favored, but also, the environment.
