| description | In order to determine the design strengths of <i>P. edulis</i> bamboo material, this research carried out a series of material tests on the full-culm <i>P. edulis</i> bamboo specimens, including compression tests parallel to the grain, bending tests, tension tests parallel to the grain, shear tests parallel to the grain and compression tests perpendicular to the grain. The standard values of different strengths for bamboo material were obtained by the Bootstrap method. The influence of the load combination and load effect ratio on the relationship between reliability index β and resistance factor γ<sub>R</sub> was analyzed. A method for calculating the target reliability index of bending strength was proposed. The design strengths of the <i>P. edulis</i> bamboo material were determined and the adjustment method considering different design situations was also put forward. The research results show that the target reliability of the bending strength of bamboo material is suggested to be 3.57. With the same β value, γ<sub>R</sub> is the maximum under the combination of constant load + snow load, and γ<sub>R</sub> is the minimum under the combination of constant load + live load on the office building floor. Under the same load combination and load ratio, the shear strength along the grain has the maximum γ<sub>R</sub> and the compression strength along the grain has the minimum γ<sub>R</sub>. The design strengths of the <i>P. edulis</i> bamboo material were determined by the larger γ<sub>R</sub> of two cases (one is that the load ratio of constant load over live load on the residential building floor is 1.0 and another is that the constant load over live load on the office building floor is 1.0). The design strengths can provide reference for the design and application of bamboo structure. |
