COC 832 - Tópicos Especiais em Modelagem Física e Numérica de Estruturas de Contenção


Desenvolver conceitos sobre modelagem física e numérica de estruturas de contenção, incluindo solo reforcados 

Ementa (Syllabus)

  1. Serão apresentadas procedimentos para modelagem física e numérica desse tipo de estruturas.
  2. Serão destacadas a influência de diversos fatores (inclinação da face, rigidez da face e dos reforços, restrições a movimentações na base e sobrecargas) no comportamento e desempenho destas sob condições operacionais.
