Description: Technical report
Abstract: This report summarizes the to-date {October 1969) results of a current WES study on the feasibility of using bamboo as an expedient reinforcement for temporary reinforced concrete structures. The report contains the results of an investigation of the most important engineering properties of an Asian species of bamboo {Phyllostachys bambusoides or Madake), same additional properties {since the publication of Report l) obtained for the local Mississippi cane (Arundinaria-tecta), description of short-time static tests conducted on 14 beams, description of tests of two beams subjected to sustained loading, conclusions, and tentative, to-date recommendations for the design of bamboo-reinforced members. Some of the principal conclusions were: Based on engineering properties, the local Mississippi cane may be inferior to most other species; however, the degree of inferiority may not be as great as originally anticipated. The shrinkage-bond problem associated with presoaked bamboo reinforcement should not be a severe problem in areas with climates similar to those found in the southeastern part of the United States. The sustained tensile strength of bamboo is considerably lower (at least 50 percent) than the tensile strength determined in conventional tests of short duration. Bamboo-reinforced members that are designed and constructed according to the tentative recommendations outlined herein can be expected to develop from two to four times the ultimate flexural load-carrying capacity of unreinforced members of equal dimension; however, one must expect wide cracks and large deflections, even at safe loading rates.
