A non-linear spring for modelling of wooden structures under seismic loading condition has been implemented as an external library in OpenSees framework. This element, previously used in the FE code ABAQUS and written in Fortran 77 language, has been interfaced with OpenSees via an ad-hoc routine. The proposed element is used in static and dynamic non-linear models of wooden structures to represent the dissipative capacity of steel connections. An example of a X-lam (cross-lam) wall is presented and a comparison with available experimental results is shown. The model is built with non-linear springs elements and quad elements characterized by linear-elastic behaviour.

Abstract
A non-linear spring for modelling of wooden structures under seismic loading condition has been implemented as an external library in OpenSees framework. This element, previously used in the FE code ABAQUS and written in Fortran 77 language, has been interfaced with OpenSees via an ad-hoc routine. The proposed element is used in static and dynamic non-linear models of wooden structures to represent the dissipative capacity of steel connections. An example of a X-lam (cross-lam) wall is presented and a comparison with available experimental results is shown. The model is built with non-linear springs elements and quad elements characterized by linear-elastic behaviour.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
