Abstract
Bamboo has a long and well-established tradition as a building material throughout the world. Bamboo has various applications such as, for furniture, bicycle structure, unmanned air vehicle structure. Despite the fact that Ethiopia has abundance bamboo, till now the tensile strength of both Oxytenanthera abyssinica (solid) and Yushania Alpina (hollow) bamboo was not studied sufficiently. This research focuses on tensile strength testing and characterization of solid and hollow bamboo found in Amhara region at Jawi and Awi district through standard test procedures. The specimens were prepared and tested according to ISO standard. The tensile strength of specimens were tested and characterized with respect to its species, age and culm position. The test result showed that tensile strength of solid and hollow bamboo without node, increases from bottom to top. Hollow and solid bamboo specimens without node had greater tensile strength than specimens with node. Besides solid bamboo without node had superior average tensile strength (ranges between 211.5 MPa to 260.2 MPa) than hollow bamboo without node (179.7 MPa to 246.1 MPa). Irrespective of the age, specious, with node and without node the lowest strength showed on the bottom portion of the specimens. The test specimen results demonstrated as the age increases from year two to four, the bottom strength increased consistently. To use bamboo for structural and related purpose it is recommended to take the bottom portion strength than the average or the highest strength for safe design.
