Modelos de cálculo de análise estrutural: estudo de caso para um edifício em concreto armado

Abstract

Structural analysis is used to determine the stresses and displacements in the structures. In this work the analyzed effort was the bending moment in beams. The main objective was to make comparisons between the results of the bending moments obtained by the different structural models. It was used the continuous beam model, flat portico model, unpaved space gantry model and space portico model with finite plate elements. With the exception of the model that uses the finite element method, the portion of the load in the corresponding beams the support reactions of the slabs were obtained by the method of plastic hinges. A commercial building of 4 equal floors was used, and only the vertical loads acting on the pavement type using SAP2000 software were analyzed. The loads were used in accordance with NBR 6120 and the concrete properties are in accordance with NBR 6118
