Influência da temperatura nas propriedades dinâmicas de um pórtico plano.

Abstract

Safety and structural integrity are highly relevant factors in the construction process. With the consolidated trend of increasingly slim and complex constructions, the importance of monitoring such factors evolves in the same fashion. In this context, the temperature gains prominence not only for its harmful effects, but also because it significantly hinders the monitoring process. Currently, there is a wide dissemination of research with the development of assisting technologies for this process, such as the application of numerical models based on the finite element method assisted by software, such as the Ansys Workbench. Due to the foregoing, this work was carried out in order to develop the analysis of the dynamic properties of a flat frame under temperatures ranging from 1°C to 40°C. A great similarity was observed between the variability of the frequencies obtained in the study with those found in similar works, which highlights the potential and practicality of using numerical models as a tool for assessing structural integrity.
