ABSTRACT

An evaluation of the seismic behaviour of post-and-beam timber buildings braced with timber shear walls by means of numerical simulations performed with non-linear elastic analysis is presented in the paper. Three different structural configurations are considered: two storeys and three storeys regular buildings and two storeys non-regular in plan building. The dissipative capacities of the systems were localized in correspondence of the connections; their non-linear behavior was assessed experimentally, numerically or analytically. The results evidenced good seismic performances in terms of global ductility and resisting ground acceleration and evidenced a similar behavior for the three analysed buildings.

KEYWORDS: timber structures, post-and-beam system, seismic behaviour, pushover analysis, ductility, non-linear behaviour, numerical simulations, sustainable structures.
