However, the modeling of assembled cross-laminated timber components has been studied only scarcely. The three-dimensional p-version of the finite element method, which is characterized by hierarchic high-order shape functions, is well suited to consider coupling and support conditions. Furthermore, a small number of degrees of freedom can be obtained in case of thin-walled structures using p-elements with high aspect ratios and anisotropic ansatz spaces. In this article, a model for cross-laminated timber assemblies made of volumetric high-order finite elements is presented. Two representative types of connections are investigated, one with an elastomer between the cross-laminated timber components and the other without. The model is validated, and suitable ranges for the stiffness parameters of the finite elements which represent the junctions are identified.}, language = {en} } @techreport{RaboldWohlmuthHorgeretal.2018, author = {Rabold, Andreas and Wohlmuth, Barbara and Horger, Thomas and Rank, Ernst and Kollmannsberger, Stefan and Frischmann, Felix and Paolini, Alexander and Schanda, Ulrich and Mecking, Simon and Kruse, Tobias and Ch{\^a}teauvieux-Hellwig, Camille and Schramm, Markus and M{\"u}ller, Gerhard and Buchschmid, Martin and Winter, Christoph}, title = {Vibroakustik im Planungsprozess f{\"u}r Holzbauten: Modellierung, numerische Simulation, Validierung: Dachbericht zum Forschungsvorhaben}, year = {2018}, language = {de} }
