ANÁLISE ESTÁTICA DE UM GAZEBO DE BAMBU LOCALIZADO NO CENTRO DE TECNOLOGIA DA UFPB

Abstract

In a globalized society, where climatic issues are gaining notoriety among people, the construction industry has sought new alternatives to minimize the impacts of its activities on the environment. This work has as general objective the analysis of the static behavior of a bamboo gazebo - considering the action of the wind that acts on the structure. It was necessary the elaboration of a numerical model that would allow the execution of the static analysis of the structure. Initially, the behavior of the bamboo sticks that supported the ecological roof under which the loads from the wind, the solar plate and the roof itself acted were analyzed. Then, the efforts on the bamboo roof were examined - in which the wind performance was not considered. Finally, the efforts were made in the porticos that supported and received the loads coming from the support rods of the roofs. Comparing the values of the maximum tensions obtained in the static analysis for each type of rod in the gazebo structure to the results of average permissible stresses for the bamboo, it was possible to observe that the tensile stresses are well below the average limit value, which is 89.96 MPa. However, some of the compressive stresses acting on the structure reach values closer to the average limit, which is 29.48 MPa. In this study, it was possible to observe that the highest stresses occurred in the support bars of the ecological roof, which is probably due to the low inertia of the cross sections of these bars and that even for the most adverse situations of load action, in cases of maximum tensile stress and maximum compression stress, the bamboo shows a material able to withstand the highest tensions acting on the structure.
