Abstract: The burgeoning of the Cross Laminated Timber (CLT) industry in recent years along with the
shift to performance-based design, has created an interest in the use of these timber
constructions, particularly in medium- and high-rises in seismic areas. However, current
European codes lack substantial guidelines for the efficient design of these structures. New
provisions based on experimental research and complemented by numerical analyses need to
be defined. In the scope of the SERIES project, a three-storey full-scale CLT building was
subjected to biaxial input motions on a shake table with Peak Ground Acceleration (PGA)
levels reaching up to 0.5 g. A numerical model of the house was developed in SAP2000 and
validated with the results obtained from the experimental tests. Special attention was paid to
the modelling of the mechanical connections in the building due to the significant role that
they play in the behaviour of the structure under lateral loads. The stiffness of the connections
was determined from prior experimental tests that had been conducted by TUGraz on the
individual connectors and walls. This paper explores the application of non-linear dynamic
analyses in the seismic performance of CLT buildings through an appraisal of the model
developed in the current paper.
