Bambu framing: proposta de um sistema construtivo não convencional

Abstract

There is an increasing need for reduction of environment impacts caused by construction work, which are a great source of natural resources consumption, solid waste and polluting gases. The substitution of traditional “handmade” construction methods by industrialized construction methods presents as a promising alternative solution, once the processes are optimized and waste is reduced. Bamboo has excelled in civil construction because of its great renewal potential and rapid growth, which allows its use for building purposes with only 3 years of age, among other advantages. Therefore, the present work proposes a sustainable construction system based in framing models of industrialized construction, by means of pre-manufactured structural glued laminated bamboo frames using the bamboo species Dendrocalamus Giganteus. A thorough review of the scientific literature about the central themes debated by this work was done, including the functioning of frame based construction systems and its mechanical and physical properties. The main objective of the present work is the presentation of a constructive system that besides being ecologically correct also has high quality standards and is able to generate a structurally safe building. Through the analysis of structural tests available in the scientific literature with glued laminated bamboo frames using D. giganteus species, its structural application feasibility could be appreciated. It is concluded that the application of glued laminated bamboo frames as a structural unit in civil construction is feasible, but technical regulatory standards are necessary, and more effort needs to be done to make it accessible and spread its application.
