It is well known within the Portuguese scientific community that the masonry ‘Gaioleiro’ buildings, built in Lisbon between the late nineteenth and the early twentieth century, represent the masonry buildings with highest structural weaknesses. In this paper, a brief description of the ‘Gaioleiro’ buildings is presented and the results of the seismic assessment of an existing building are discussed. The structure was modelled based on the nonlinear equivalent frame model approach considering Tremuri Program (Lagomarsino et al., 2012). The in-plane capacity curves were determined with incremental static (pushover) analysis, supported on the assumption that the out-of-plane failure of the walls is prevented by adequate retrofitting measures. The main goal is to point out the seismic response of ‘Gaioleiro’ buildings in Lisbon, being the definition of the fragility curves for this typology of buildings the ultimate aim of the study.

Abstract
It is well known within the Portuguese scientific community that the masonry ‘Gaioleiro’ buildings, built in Lisbon between the late nineteenth and the early twentieth century, represent the masonry buildings with highest structural weaknesses. In this paper, a brief description of the ‘Gaioleiro’ buildings is presented and the results of the seismic assessment of an existing building are discussed. The structure was modelled based on the nonlinear equivalent frame model approach considering Tremuri Program (Lagomarsino et al., 2012). The in-plane capacity curves were determined with incremental static (pushover) analysis, supported on the assumption that the out-of-plane failure of the walls is prevented by adequate retrofitting measures. The main goal is to point out the seismic response of ‘Gaioleiro’ buildings in Lisbon, being the definition of the fragility curves for this typology of buildings the ultimate aim of the study.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
