Abstract

A numerical modelling approach for the prediction of the seismic response of multi-storey CLT buildings is proposed. The approach is based on a simplified phenomenological model where the behaviour of the CLT system is reproduced by means of an equivalent elastic modulus assigned to the CLT wall in order to account for both the connections and panel deformability. Phenomenological modelling aims to reproduce faithfully the global response of the structural system in terms of principal elastic period, internal forces in the connection elements and inter-storey drifts. Results of a multy-parametric analyses carried out on different CLT walls, deigned considering increasing level of seismic intensity, are presented and discussed. A design abacus that allows designers for a direct implementation of the proposed phenomenological model and therefore an easy and efficient seismic analysis of a CLT building is finally proposed.
