Flexural Properties of Multiple Bamboo Beams with Connection Joints

Bamboo is a natural material widely used in buildings and bridges that has good mechanical properties. However, the longitudinal connection of bamboo culms major problem for industry. In this study, sleeve-nailed specimens were produced, which contained three pieces. Two pieces with similar diameters longitudinally joined by inserting short culm smaller diameter, fixed nails. The flexural performance single beams two-culm studied. load-displacement curves fracture behavior investigated. results show bearing capacity connected specimen was relatively than an unconnected one, while beam improved significantly. It can be seen lateral improve combined culms. This study provides basis promoting application sleeve-type nailed connections bamboo.
