Brick industrial chimney

The industrial chimneys executed on the basis of a brick factory were one of the most emblematic elements of industrial architecture. Its construction derived from the need for the extraction of fumes from steam engines and the circulation of air that facilitated combustion, strongly marking the landscape that surrounded them.

The industrial chimneys executed on the basis of a brick factory were one of the most emblematic elements of industrial architecture. Its construction derived from the need for the extraction of fumes from steam engines and the circulation of air that facilitated combustion, strongly marking the landscape that surrounded them.

Currently, many of the examples of industrial architecture existing in Portugal are abandoned, given to a degradation accentuated by years of neglect. In spite of everything, there are still several industrial complexes where some emblematic fireplaces resist to the caprices of the abandonment and lack of maintenance.

The study fireplace was part of a ceramic elements factory founded in 1910 and represents an excellent example of the industrial architecture of the early s. XX. Its environment, which has undergone a deep development in the last ten years, has become a cultural and recreational area, turning the chimney into a singular construction to conserve. Like many other specimens of the same period, the chimney is built of solid bricks bound with lime mortar, with a maximum height of about 40 m.

The intervention of NCREP in the chimney consisted in the realization of a geometric survey through Laser Scanning technology, in the visual inspection in all its height, with registration of the points with damages and the intensity of these in own maps, and in the conducting a campaign of dynamic identification tests in situ, studying the environmental vibration. Finally, all the results collected served as the basis for the development of a numerical model of finite elements, with non-linear behavior, with the aim of evaluating their structural safety considering the usual acting actions.
