Deck boards : stress grading and identification for Connell Wagner

"In September 1991 Mr Al Austin of Connell Wagner contracted the TWP to evaluate a sample of deck boards taken froma floating-pontoon-type helicopter pad. Using in-grade techniques, the Modulus of Elasticity (MoE) and Modulus of Rupture (MoR) were determined. The density of the wood was determined both for air-dry Equilibrium Moisture Content (EMC) and oven dry (0%) moisture content. The mean failure load for bearer-to-bearer span of 900 mm was calculated to be 7.4 kN (2P, 4 point loading)."--p. (i).
