The bamboo presents low consumption of energy and low cost of production, beyond being a renewable and ecological material. It is a potentially promising material that comes demonstrating great qualities for the civil construction. Studies had shown that the relation tensile strenght and specific weight of the bamboo is 2,77 times bigger that of the steel. This thesis presents the results of an experimental investigation to establish the physical, mechanics and meso-structural, of the bamboo of the species Guadua weberbaueri for possible application in the civil engineering as a non- conventional material. The results of the mechanical rehearsals showed compatible values to other researched species. It was concluded that the material when subject to traction loads, shear or compression presented similar behavior to the of other studied species already, since 1979, in the Department of Civil Engineering of PUC-Rio, under the orientation of professor Khosrow Ghavami. Where some programs of inquiry for the vegetal job of the bamboo and other staple fibers in the construction of edifications of low cost had been developed, substituting pollutant products of asbestos, steel, cement and other pollutant materials didn´t renew. Being able this being used as non-conventional material in civil engineering.
