Self-centering rocking mechanisms combined with dissipative bracing systems is a passive control technology that can prevent structural and non-structural damages and minimize residual drifts during strong earthquakes. An experimental campaign has been performed at the structural laboratory of the University of Basilicata on a 2/3 scaled, 3-dimensional, 3-storey post-tensioned timber framed building with dissipative bracing systems. It is part of a main project that involved shaking table tests on the specimen in different configurations considering different energy dissipating systems. This paper focuses on the numerical modelling of post-tensioned timber framed (Pres-Lam) buildings with dissipative bracing systems. Preliminary nonlinear dynamic analyses were performed and compared with global and local experimental behavior, providing a suitable representation of the seismic response.

Abstract
Self-centering rocking mechanisms combined with dissipative bracing systems is a passive control technology that can prevent structural and non-structural damages and minimize residual drifts during strong earthquakes. An experimental campaign has been performed at the structural laboratory of the University of Basilicata on a 2/3 scaled, 3-dimensional, 3-storey post-tensioned timber framed building with dissipative bracing systems. It is part of a main project that involved shaking table tests on the specimen in different configurations considering different energy dissipating systems. This paper focuses on the numerical modelling of post-tensioned timber framed (Pres-Lam) buildings with dissipative bracing systems.
