The paper investigates the influence of modelling different types of connections in multi-storey cross-laminated timber buildings. The importance of modelling the connection flexibility in the prediction of the natural vibration periods and the base shear force of a crosslam building is demonstrated using linear dynamic analysis. The building’s global ductility and peak ground acceleration were compared using non-linear static and dynamic analyses, demonstrating that the former may lead to non-conservative result. The effect of gravity loads does not seem to be crucial in the analyses, whereas including friction in the model leads to a lower seismic response of the structure. This beneficial influence may however be reduced by the vertical component of the seismic acceleration, not considered in this study.

Abstract

The paper investigates the influence of modelling different types of connections in multi-storey cross-laminated timber buildings. The importance of modelling the connection flexibility in the prediction of the natural vibration periods and the base shear force of a crosslam building is demonstrated using linear dynamic analysis. The building’s global ductility and peak ground acceleration were compared using non-linear static and dynamic analyses, demonstrating that the former may lead to non-conservative result. The effect of gravity loads does not seem to be crucial in the analyses, whereas including friction in the model leads to a lower seismic response of the structure. This beneficial influence may however be reduced by the vertical component of the seismic acceleration, not considered in this study.
