Compared with Moso bamboo,Phyllostachys edulis,the wood mechanical properties of Bambusa wenchouensis,a sympodial bamboo,were studied.The result showed that its tensile strength parallel to grain(δt),compressive strength parallel to grain(δc),cleavage strength(C) and modulus of elasticity in static bending(MOE) were 238.0 MPa,75.1 MPa,45.6 N·mm-1 and 12.6 GPa respectively,which were larger than or almost equal to those of Moso bamboo.Its shearing strength parallel to grain(δs) and bending strength(MOR) were smaller.The wood mechanical properties of B.wenchouensis had good relativity with each other,and the δt∶δc∶δs∶C∶MOR was equal to 3.2∶1.0∶0.2∶0.6∶1.8.This study could lay theoretical foundation for proper exploiture and utilization of B.wenchouensis.
