Experimental Study on Mechanical Properties of Hainan Rubberwood
Wood structures are receiving attention in construction due to their green,low-carbon qualities,high prefabrication rates,and efficient construction.Hainan rubberwood,with its abundant plantation resources,is mainly used for furniture boards,but its application as a structural material is limited,and comprehensive performance indicators are lacking.Mechanical properties of rubberwood,including bending along the grain,compression along the grain,compression across the grain,tension along the grain,and shear along the grain,are tested to determine standard and design strength values.Full-size rubberwood dimension lumber is visually graded,with flexural modulus and flexural strength tested across different grades and compared to imported wood.Results show that rubberwood exhibits favorable mechanical properties,meeting the TB13 strength grade requirements of wood structure design standards,except for tensile strength along the grain.The bending performance of rubberwood varies with visual grading,yet surpasses that of commonly used imported dimension lumber,providing reference for its use as a structural material in construction engineering.
