WebJan 1, 1974 · The rolling shear modulus measured was then used as input to predict, using the shear analogy method, the deflection (d c) of a 3-layer CLT beam subjected to the centre-point bending load. Subsequently, the bending test was conducted to directly obtain the deflection (d m) of a 3-layer CLT beam for validation. It was found that d c … WebWe perform the test in house here and not to a defined ASTM standard (at this time).
