Análise comparativa dos modelos de pórticos planos associados e dos pórticos espaciais

Abstract

ABNT – NBR 6118:2014 establishes conditions for the use of structures, under the ultimate limit states and service limit states. Therefore, there are robust models capable of providing the efforts and deformations under the loads combinations by the standard, among them are the associated plane frame models and the spatial frame model. In order to compare these two structural models, this work will present a comparative analysis of the efforts of bending moment and axial force, displacements and global stability through these structural models applied, respectively, in the FTOOL and SAP2000 softwares, from a model of construction. So, this work resulted, based on an analysis of a column alignment, a structure with biggest displacements and efforts from the modeling via SAP2000, that is, by spatial frames. Therefore, this modeling presented more favorable results for safety
