The heritage value of the mixed wood-masonry 18th century Pombalino buildings of downtown Lisbon is recognized both nationally and internationally. The present paper focuses on the seismic assessment and retrofitting of a typical Pombalino building by nonlinear static analyses. Seismic performances of different configurations (by considering also various retrofitting strategies) are compared by the definition of fragility curves and damage probability plots. The used software has been the structural program called Tremuri with which nonlinear static analyses have been performed. The structure is modelled using nonlinear beams for masonry panels; in case of the internal walls (frontal walls) an original formulation has been developed in order to take into account their specific seismic behaviour. Seismic assessment has been evaluated by applying nonlinear static procedures. Finally, assuming a lognormal distribution probability function, fragility curves are obtained to be representative of Pombalino buildings classes: the most important application of such curves is for seismic loss estimation studies.
