Abstract (EN):
At the end of the XIX and the beginning of the XX century there was a considerable
industrial development in Portugal, characterized by the flourishing of several industrial
plants. Brick masonry chimneys represent some of the most interesting examples of the
industrial architectural heritage. The paper shows the case study of a chimney from a former
ceramic factory near Porto city and that now is part of a cultural and leisure public park.
With the main goal of evaluating the seismic vulnerability of existing structures, numerical
models are often used without the proper knowledge of their mechanical characteristics. The
focus on this paper is given on the construction of a realistic numerical model based on a
detailed in-situ survey of the chimney, involving: geometrical characterization; visual
inspection, with damage registration; structural/material assessment, based on in situ dynamic
tests. Two different approaches regarding the chimney damage state were followed for the
calibration of the numerical model. The models from both approaches were then subjected to
accelerograms matching the chimney site conditions and the responses were compared,
underlining the importance of a good mechanical characterization of the materials involved.
