OTIMIZAÇÃO DA MALHA DE ELEMENTOS FINITOS VIA SOFTWARE ANSYS EM NÚCLEO C CONTRAVENTADO POR LINTÈIS

Abstract

The modeling of structures via Finite Elements is quite usual nowadays, in view of its importance, this research was developed in order to provide subsidies to the modeling of reinforced concrete columns in thin walls of C cores braced by horizontal lintels in X and Z over the modeling possibilities through the commercial software Ansys. This paper presents the initial procedures necessary for the insertion of the geometry in the program platform and a comparison between the 3 types of existing meshes, Hexahedral, Tetrahedral and Prismatic, demonstrating their respective convergences, through data and analysis in the specified cases, exhibiting an accuracy of 96.25% in the 1st Vibration Mode of the column with horizontal lintels, an error notwithstanding 5% in the column with lintels arranged in X and an error less than 2% in the column with lintels arranged in Z.
