Experimental Research on the Compressive Performance of Raw Bamboo Materials along the Grain

This paper carried out a compression test along the grain of the raw bamboo material, analyzed the failure process and failure form of the specimen, studied the relationship between the compression strength along the grain and the elastic modulus and the density, and initially explored the raw bamboo based on the reliability analysis Design value of compressive strength along the grain of the material. The research results show that the compressive load-displacement curve of bamboo along the grain can be divided into elastic, elastoplastic and descending segments, and the specimens show obvious ductile failure characteristics; the compressive strength and elastic modulus along the grain are positively correlated with the density; raw bamboo The standard value of compressive strength along the grain of the material is 48.83MPa, and the design value is 8.71MPa.
