Abstract(s)
Neste trabalho é estudado o comportamento teórico de vigas de betão de
ultra elevado desempenho reforçado com fibras metálicas sujeitas à torção,
demonstrando evidências experimentais e introduzindo uma nova
metodologia para a extensão do modelo GSVATM unificado, proposto e
validado por Bernardo e Andrade [1].
Para que isso aconteça, são descritas as evidências experimentais ensaiadas
à torção por Yang et al [2] e Zhou et al [3], as quais contam com vigas de
ensaio que tem determinadas características que são importantes e que
serão alvo de referência. Será determinada a lei constitutiva das fibras
metálicas, determinadas as novas equações de equilibro e compatibilidade,
que farão parte do algoritmo proposto.
In this work the theoretical behavior of ultra high performance concrete beams reinforced with metal fibers subject to torsion is studied, demonstrating experimental evidence and introducing a new methodology for the extension of the unified GSVATM model, proposed and validated by Bernardo and Andrade [1]. For this to happen, the experimental evidence tested to torsion by Yang et al [2] e Zhou et al [3] are described, which have test beams that have certain characteristics that are important and that will be the target of reference. The constitutive law of the metallic fibers will be determined, the new equilibrium and compatibility equations will be determined, which will be part of the proposed algorithm.
