Abstract
Novel high-performance bamboo-based composite materials (HPBBC) being used instead of other building materials is a direction that cannot be ignored in the carbon peaking and carbon–neutral process. A series of mechanical property tests is carried out in this study, and statistics and structural reliability design theory are introduced to calculate the design strength of HPBBC materials. Based on material testing damage characteristics, the design strength reliability indicator in compression is 3.2, while this value is 3.7 in bending and tension. The results show that the design strength satisfying reliability requirements in the compression, tensile, and bending of the HPBBC material are 74.6 MPa, 138.4 MPa, and 146.9 MPa respectively. In addition, the design strength-to-weight ratio of HPBBC in compression and tension is 1 and 2 times that of A615-Grade 80 steel, respectively. The HPBBC material is a renewable, high-strength, and lightweight green material. The results of this study can be used as a reference for the design and use of HPBBC materials.
