Numerical analysis of the structural behavior of flat plates under tension loads

Resumo

Based on the guidelines provided by the ABNT NBR 8800 [1], the present study analyzes the
prescription for determining the strength of cross-sections with holes arranged straight or zigzag for elements
subject to tensile load. In case of misaligned holes, these calculations are performed by a semi-empirical parameter,
defined by the Cochrane equation. This additional parameter covers an increase of resistance from an additional
equivalent portion of the cross-sectional area. In this work, it is intended to simulate numerically the structural
behavior of flat steel plates under tensile stress through a finite element modeling processed by Ansys 16.0 and
verify the compatibility with the analytical methods prescribed by the code. Three plates were modelled according
to the study by Oliveira and Wietzikoski [2] to attest the collapse modes, rupture profile, and resistance obtained
experimentally and validate the analytical prescriptions from the results of the numerical modeling.
