Abstract
Bamboo is a renewable natural building material with good mechanical properties. However, due to the heterogeneity and anisotropy of bamboo stalk, a large amount of material performance testing costs are required in
engineering applications. In this work, longitudinal compression, bending, longitudinal shear, longitudinal tensile,
transverse compression and transverse tensile tests of bamboo materials are conducted, considering the influence
of the bamboo nodes. The mechanical properties of the whole bamboo stalk with the wall thickness and outer
circumference are explored. Through univariate and multiple regression analysis, the relationship between
mechanical properties and wall thickness and perimeter is fitted, and the conversion parameters between different
mechanical properties are derived. The research results show that the transverse compressive strength of nodal
specimen, and transverse tensile strength of nodal and inter-node specimens increase with the increase of wall
thickness and outer circumference, but other mechanical properties decrease with the increase of wall thickness
and outer circumference. The prediction formula and conversion parameters of bamboo mechanical properties
proposed in this research have high applicability and accuracy. Moreover, this research can provide references
for the evaluation of bamboo performance and saving test costs.
