COC818 - Tópicos Especiais em modelagem numérica de aterros estruturados

Objetivos

Desenvolver conceitos sobre modelagem numérica 2D e 3D de aterros estruturados 

 

Ementa (Syllabus)

1. Introdução ao método dos elementos finitos e aplicação de modelagem numérica em geotécnica
2. Etapas principais para a simulação numérica de condições reais do campo
3. Serão destacadas a influência de diversos fatores (modelos constitutívos, etapas construtivas, rigidez e espaçamento dos reforços, e condições geométricas) no comportamento e desempenho destas
