- Cross-laminated timber (CLT) is a board molded designed wood item, amassed of cross-wise situated layers of lamellas. Subsequently, anticipating the particular conduct of such boards requires exact data about their twisting and shear quality and additionally their flexible properties. Directions with respect to the inference of execution qualities, assessment of similarity and stamping of wood-based boards for use in development are given in EN 13986. As per this standard bowing quality and stiffness of CLT must be evaluated following the system in EN 789. The last requires 4-point twisting trial of strip-formed examples with a width of 300 mm, remove the CLT boards. The traverse must be taken as 300 mm + 32 t, t being the ostensible thickness of the CLT board. By looking at aftereffects of bowing tests on strip-formed examples and on full boards it is appeared, that neither quality nor stiffness properties determined by testing strip-molded boards are suitable to survey the separate properties of the first boards. Moreover a check via doing static twisting tests (diversion estimations) under various stacking circumstances appeared, that the general stiffness properties (versatile parameters of the stiffness network) can, on the other hand to EN 789 tests or estimations with the compound hypothesis, be determined straightforwardly by a modular investigation of full-measure CLT boards.
