Recently, in the attention in response to global warming issues and sustainable society, the manufacturing using natural materials has become actively. Bamboo, low cost, fast growing, and broad distribution of growth, is expected to contribute significantly to earthquake-resistant construction and seismic retrofit technology in the developing countries. This paper investigates the mechanical properties of bamboo reinforced concrete beams. It compares these experimental results of bamboo reinforced concrete beams with the experimental ones of reinforced concrete beams and the mechanical property of the bamboo reinforced concrete beams is studied. From these experimental works, the possibility of effective using of ‘Bamboo' is discussed.
