DENSITY CALCULATION METHOD OF WOODEN COMPONENT, AND YOUNG'S MODULUS CALCULATION METHOD OF WOODEN COMPONENT

摘要

PROBLEM TO BE SOLVED: To calculate a density of a wooden component in the built-in state into an architectural structure.;SOLUTION: A density calculation method of a wooden component has steps for: measuring a perforation resistance value received by a drill when perforating a testing wood with the drill, and a density of the testing wood, and determining a regression line using the perforation resistance value and the density as two variables; and measuring the perforation resistance value received by a drill by perforating the wooden component with the drill, and calculating the density of the wooden component from the regression line.;SELECTED DRAWING: Figure 6;COPYRIGHT: (C)2017,JPO&INPIT
