O MAPA SÍSMICO E SUA INFLUÊNCIA NA CONSTRUÇÃO CIVIL NO SUL DE MINAS GERAIS

Abstract

This article draws attention to the new seismic map that is already a reality in the academic environment but that still does not interfere with anything in the norms to be built. The construction processes with the possibility of an earthquake are still guided by an outdated standard based on a worldwide scale. In view of this, it is necessary to make an analysis of NBR 15421/2006 taking into account the new map developed by the Brazilian seismology network in observation of the behavior that the land has shown over these years of monitoring, making the data instruments for the construction of new ones. norms and expansion of existing ones addressing points that are not yet covered, such as bridges, viaducts and other works that need standardization. In view of this need for adequacy, the NBR 15421 seismic map points to calculations based on a single type of rock, not considering the characteristics of the soil or seismicity of the southern region of Minas Gerais, with its constructions marked by the current standard, generating vulnerability in the face of magnitudes that can cause damage to property and life.
