Prediction of Mechanical Properties of Structural Bamboo and Its Relationship with Growth Parameters

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