Fragility functions for tall URM buildings around early 20th century in Lisbon....
Simoes, Ana G.; Bento, Rita; Lagomarsino, Sergio; Cattari, Serena; Lourenço, Paulo B.This article describes the application of the procedure for the derivation of fragility functions presented in the companion article entitled Fragility functions for tall URM buildings around early 20th century in Lisbon. Part 1: methodology and application at building level. The procedure, based on the execution of non-linear analyses, was developed to be applied to unreinforced masonry buildings considering b...
Fragility functions for tall URM buildings around early 20th century in Lisbon....
Simões, Ana G.; Bento, Rita; Lagomarsino, Sergio; Cattari, Serena; Lourenço, Paulo B.The article proposes a procedure for the derivation of fragility functions for unreinforced masonry buildings considering the in-plane and out-of-plane response. Different approaches are considered for the generation of the corresponding fragility functions and for the evaluation of the propagation of uncertainties. The contributions for the dispersion of the fragility functions account for the variability in t...
Architectural and Structural Characteristics of Masonry Buildings between the 1...
Simoes, Ana G.; Appleton, Joao G.; Bento, Rita; Caldas, Joao V.; Lourenço, Paulo B.; Lagomarsino, SergioThe masonry buildings constructed between the 19th and 20th centuries in Lisbon are commonly recognized for their eclectic style and structural vulnerability. This article presents the main characteristics of these buildings in the aim of preserving their cultural value. The socio-economic conditions on what they were constructed are identified. This includes the possible reasons for the negative impression att...
Methods and approaches for blind test predictions of out-of-plane behavior of m...
Mendes, Nuno; Costa, Alexandre A.; Lourenço, Paulo B.; Bento, Rita; Beyer, Katrin; de Felice, Gianmarco; Gams, Matija; Griffith, Michael C.Earthquakes cause severe damage to masonry structures due to inertial forces acting in the normal direction to the plane of the walls. The out-of-plane behavior of masonry walls is complex and depends on several parameters, such as material and geometric properties of walls, connections between structural elements, the characteristics of the input motions, among others. Different analytical methods and advanced...
Seismic vulnerability and risk assessment: case study of the historic city cent...
Vicente, Romeu; Parodi, Sonia; Lagomarsino, Sergio; Varum, Humberto; Silva, J. A. R. MendesSeismic risk evaluation of built-up areas involves analysis of the level of earthquake hazard of the region, building vulnerability and exposure. Within this approach that defines seismic risk, building vulnerability assessment assumes great importance, not only because of the obvious physical consequences in the eventual occurrence of a seismic event, but also because it is the one of the few potential aspects...
A mechanical model for the seismic vulnerability assessment of old masonry buil...
Pagnini, Luísa Carlotta; Vicente, Romeu; Lagomarsino, Sergio; Varum, HumbertoThis paper discusses a mechanical model for the vulnerability assessment of old masonry building aggregates that takes into account the uncertainties inherent to the building parameters, to the seismic demand and to the model error. The structural capacity is represented as an analytical function of a selected number of geometrical and mechanical parameters. Applying a suitable procedure for the uncertainty pro...
