INFLUENCE OF CONNECTING ELEMENTS IN HORIZONTAL LOAD-BEARING SYSTEM OF A MASS TIMBER OFFICE BUILDING

This paper presents an analysis of the behaviour of a wooden building and its dynamic parameters, considering different methods of modelling the connections between elements, with a focus on the structural elements that are part of the horizontal load-bearing system. The building's structural elements are made of GLT, CLT, and LVL components, with a unique horizontal load-bearing structure consisting of diagonals and a core made of CLT panels. Special attention is given to the connections of the core and the modelling of their impact on the response of the structure. A parametric analysis was conducted on four models, each employing different methods of modelling the connections between the CLT panels of the core. Based on these models, a comparison of the primary dynamic parameters, internal forces in the elements, and internal forces in the connections was made. Finally, the conclusion is drawn regarding the impact of different modelling methods on the dynamic parameters and internal forces.
