Correlation between NDT and Tensile Strength of Structural Larch Sawn Lumber

Abstract:

With Larch timber as the experimental subject, according to the visual grading-related rules in ASTM D245, four-point bending edge-wise in ASTM D4716-05 and axial strength in tension, the regression analysis is conducted; investigate the correlation relationship of Kus, E4s and σw. The result demonstrates that the combination of visual grading, density and four-point bending MOE, the predict of the parallel tensile strength will be more exactly whose correlation coefficient is 0.750.
