Modeling and calculation of panel buildings made of cross-laminated timber

Abstract

Buildings made using cross-laminated timber have become widespread over the last decade. The experience of designing and operating such buildings of various functional purposes confirms the expediency of their construction and use. This article provides a solution to the problem of modeling and calculating panel houses made of cross-laminated timber using the finite element method using the given mechanical characteristics of the material. The possibility of modeling and calculating panel buildings made of cross-laminated timber using the finite element method with the use of flat finite elements, taking into account the orthotropic properties of the material, under the condition of using the reduced modulus of elasticity according to the previously proposed method and adjusting Poisson's coefficients, in such a way as to maintain the condition of existence of elastic potential. The algorithm for modeling panel buildings made of cross-laminated timber using the finite element method as a system "soil base-foundation-above-ground structure system" is given.
