Building constructions made of cross-laminated timber become more and more widespread. Experience in the timber structures design and operation for various purposes confirms the feasibility of their use. Recently, the construction of prefabricated cross-laminated timber houses has become especially widespread. The problem solution of cross-laminated timber panels calculation by means of a finite element method with the material`s reduced mechanical characteristics application is offered in this article. The specified formulas for definition of the reduced geometrical and mechanical characteristics of cross-laminated timber panels` various types, including those made of combined cross-laminated timber, are resulted. The algorithm of cross-laminated timber panels calculation by means of a finite element method is resulted. The possibility of using flat finite elements taking into account orthotropic properties for the calculation of cross-laminated timber panels using the elasticity above modulus according to the above method, adjusting the Poisson's ratios so as to preserve the condition of elastic potential in timber, is reasoned.
