Computational Modeling for Evaluation of Plane Frames in Seismic Zones

Resumo

Seismic events, also known as earthquakes, induce dynamic effects on structures due to the abrupt movement of the ground, potentially leading these structures to collapse. These earthquakes are often associated with the movement of tectonic plates and primarily occur in regions near the edges of these plates, where interactions are more intense. However, there exists a specific category of earthquakes called induced seismic events, which are triggered by human activities such as mining, natural resource extraction, and fluid injection into the ground. There has been an increase in the occurrence of these earthquakes in some countries, raising concerns among authorities, especially in urban areas. In this context, our work aims to present a computer program for the dynamic analysis of plane frames, focusing on the structural behavior of such frames under the influence of seismic events. We consider seismic actions as stipulated in the Brazilian standard NBR 15421/23, as well as real induced earthquakes. The results obtained are essential for understanding the behavior of the analyzed structures and are necessary to ensure proper structural design, providing greater safety when these structures are subjected to this type of action.
