Solid State Phenomena Vol. 380

Abstract: The article proposes a methodology for calculating CLT panels as composite beams. This approach allows for the analysis of panels with any number of layers. It is shown that, unlike existing approaches, the behavior of the panel is considered in two directions, rather than as a beam system. Initially, the stiffness characteristics of the panel are determined in each direction, taking shear into account. Then, the slab is analyzed as an orthotropic plate with different stiffness characteristics in mutually perpendicular directions. This calculation is performed either as an orthotropic solid plate or as a cross-laminated beam system. To determine the stiffness characteristics in each direction while considering the shear of the cross-layer boards, the theory of composite beams is used. Taking into account the boundary conditions, the system of differential equations is reduced to a system of algebraic equations by expanding the unknowns and external load in Fourier series.
