Title: Structural analysis of a masonry chimney - in-situ assessment tools
Issue Date: 2008
Abstract: At the end of the XIX and the beginning of the XX century there was a considerableindustrial development in Portugal, characterized by the flourishing of several industrial plants.Brick masonry chimneys represent some of the most interesting examples of the industrialarchitectural heritage. The paper shows the case study of a chimney from a former ceramic factorynear Porto city and that now is part of a cultural and leisure public park. With the main goal ofevaluating the seismic vulnerability of existing structures, numerical models are often used withoutthe proper knowledge of their mechanical characteristics. The focus on this paper is given to theanalysis of the seismic behaviour of the chimney using a realistic numerical model constructedbased on detailed in-situ survey, involving: geometrical characterization; visual inspection, withdamage registration; structural/material assessment through in situ dynamic tests. Two differentapproaches regarding the chimney damage state were followed for the calibration of the numericalmodel. The models from both approaches were then subjected to accelerograms matching thechimney site conditions and the responses were compared, underlining the importance of a goodmechanical characterization of the materials involved too.
