Abstract

The modulus of elasticity and bending strength of 45 structural Salzmann pine timber pieces with nominal dimensions of 150x200x5400 mm3 from an existing 18th century structure were estimated by semi-destructive density estimation probing method (drilling chips extraction) and acoustic wave velocity (stress and ultrasound wave). Bending strength, modulus of elasticity and density were obtained according to the EN 408 European standard, and visual grading singularities were recorded. Visual grading methods are highly ineffective for existing timber structures. Sample mechanical properties show a typical profile of material from existing structures, and this was compared with the results of similar works. MOE and MOR predictive models were proposed with determination coefficients r2 of 66–68% and 51–52%, respectively, using dynamic MOE, relative edge knot diameter and slope of grain as independent variables. MOR prediction improved when these grading parameters were included.

  • Non-destructive testing techniques are commonly used to estimate the mechanical properties of standing trees, logs, sawn timber and to evaluate existing timber structures.

    “Non-destructive testing (NDT) techniques are commonly used to estimate the mechanical properties of standing trees, logs, sawn timber and to evaluate existing timber structures [25 -32].”

    From Grading of recovered Norway spruce (Picea abies) timber for structural purposes (2023) · cites this paper as [32]

    Section 1.7 (NDT support; page unavailable) says NDT has been studied for grading new timber and, more recently, for assessing timber in existing structures. It does not address NDT use for standing trees or logs, so those parts of the claim are not supported by this paper. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
