摘要

The present invention relates to a method and system for predicting expansion and contraction deformation behavior according to a change in moisture content of a structural laminate (CLT) used as a structural member in a wooden building, and the present invention relates to a structural laminate Structural use can more accurately three-dimensionally analyze the dimensional change according to the difference in moisture content of the structural panel panel, which was previously analyzed one-dimensionally, by acquiring an image for each moisture content of the member with an imaging device and quantifying and analyzing it with an image processing technique The present invention relates to a method for predicting expansion and contraction deformation of an aggregation plate and a system therefor. According to the method and system for predicting expansion and contraction deformation behavior according to the change in the moisture content of the structural laminated plate provided in the present invention, the image of the structural laminated wood specimen photographed by the moisture content step by step using the imaging equipment is analyzed using a digital image processing technique. By quantifying the degree of dimensional change, it is possible to three-dimensionally analyze the dimensional change due to the difference in the moisture content of the wood panel, and through this, it is possible to predict the shrinkage and expansion deformation according to the moisture content change of the structural aggregation board with higher accuracy. In addition, according to the deformation behavior prediction method and system of the present invention, the dimensions according to the change in moisture content of the structural laminated plate with basic wood information such as the number of layers, tree species, wood grade, width, and thickness of the laminated plate layers constituting the laminated structural laminated plate By providing a deformation prediction calculation formula that can quantitatively estimate and calculate the change, it is possible to accurately predict the shrinkage and expansion deformation caused by the change in the moisture content of the structural laminate to a degree very similar to the actual behavior. Institutions will be able to more clearly and objectively evaluate the dimensional stability of their products, and at the same time, the effect of increasing consumer confidence in the product can be expected.
