The use of bamboo as structural element is a reality in many countries in Asia and South America, even with different building methodologies. Although some bamboo species, as Moso (Phyllostachys Pubescens) have excellent mechanical properties, its diffusion as a building element conflicts with the difficulty on conceiving efficient connection systems between structural elements. Given that joints are the weak point of the structure, collapse may occur even when the structural element is intact. This research aimed to evaluate the influence of connection systems on the structural performance of plan trusses built with three different connection systems subjected to similar load conditions. By comparing the strengths obtained on the characterization tests of compression (41 MPa), tension (146 MPa) and shear (10 MPa) to the acting stresses on the truss bars in the moment of collapse, it was noted that bamboo mechanical properties were underused, once the collapse of the tested structures always started by the connections. |
