The seismic behaviour of cross-lam (cross-laminated, X-lam in the following) buildings has been analysed using the experimental results provided by SOFIE Project [1] on three and seven storey structures tested on shaking table. Two numerical models have been developed using the component approach presented in [2], where all the wooden parts are considered as elastic and the connectors are modelled with elastic-plastic springs with a predefined hysteretic rule. The developed springs can take into account stiffness and strength degradation, pinching, the friction effect and axial-shear strength interaction.

Abstract

The seismic behaviour of cross-lam (cross-laminated, X-lam in the following) buildings has been analysed using the experimental results provided by SOFIE Project [1] on three and seven storey structures tested on shaking table. Two numerical models have been developed using the component approach presented in [2], where all the wooden parts are considered as elastic and the connectors are modelled with elastic-plastic springs with a predefined hysteretic rule. The developed springs can take into account stiffness and strength degradation, pinching, the friction effect and axial-shear strength interaction. Non-linear dynamic analyses have been carried out on the models, and the results compared with the experimental data, showing an overall good agreement.
