Numerical modeling of the stress and strain state of the joint of clamped panels.

Numerical modeling of the stress-strain state of the CLT (Cross Laminated Timber) panel connection node during resistance to shear forces was performed. Comparison of the numerical experiment results with the results of full-scale tests revealed the correspondence of the nature of volumetric deformation of the steel element. 3D scanning of steel elements before and after testing with an Artec Space Spider scanner with an accuracy of 0,05 mm was used, which showed the prospects of this method for analyzing the deformations of the tested samples. An array of data was obtained for the development and correction of the analysis of the test results of the numerical model. A conclusion was made about the need for a set of studies devoted to the study of the elastic properties of CLT structures, spatial variability of the modulus of elasticity relative to the main axes of CLT structures.
