Keandalan Modulus of Elasticity (MOE) untuk Menduga Kekuatan Kayu Bercacat Akibat Lubang Bor (The Modulus of Elasticity as Predict the Strength of Drilled Wood)

Abstract

Jfany standards S'..i,h as PKKI NI-5 1961, SII-0458 1981, SKI C-bo-010-1987, SNI 03-35271994, and ASTM D245, stated strength ratio is very important indicate to adjust the allowable stress of wood However the mechanIcal grading has been developed recently so strength ratio is not necessary anymore. This research is conducted to evaluaJe the ability of Modulus of Elasticity as a single variable to grade the sound wood and defected ....ood In this research drilled hole represents as wood defect. This research saw that eventhough wood has been driiled, each variable (MOE apparent measured by Panter or UTM, or MOE true) is good enough to predict the MaR
