Abstract:
Preliminary results of a study of the feasibility of using bamboo as an expedient reinforcement for temporary reinforced concrete structures are summarized. Tentative design and construction recommendations for the use of bamboo as an expedient reinforcement are formulated. Bamboo has a ten-sile strength as high as 54,000 psi (3800 kg/cm2), but its modulus in tension is less than one-tenth of that of steel. Thus, bamboo-reinforced members tend to have large deflections and wide cracks when loaded to capacity. Bamboo-reinforced members, designed and built as suggested herein, should develop two to four times the ultimate flexural load-carrying capacity of unreinforced members of equal dimensions.
