Numerical Modeling of Reinforced Concrete and EPS Core Sandwich Panels under Bending

Resumo

The use of construction systems based on the use of Sandwich Panels has grown significantly in the
Brazilian civil construction market in recent years, with greater application in residential buildings. However, due
to the absence of normative regulation and reliable calculation standards, this system is often used without a
fundamental understanding of its structural behavior. Thus, in order to evaluate the resistant capacity of these
panels when subjected to bending forces, this work consisted of the elaboration of a three-dimensional numerical
model of a Sandwich Panel of reinforced concrete with EPS core and metallic connectors, being used the ABAQUS
for its conception, which is a software based on the Finite Element Method (FEM). In addition, the model considers
the non-linear behavior of materials, through the use of the Concrete Damage Plasticity model (CDP) and the
Plasticity model for steel, which is calibrated and validated by experimental studies present in the literature,
presenting results in agreement with those obtained by the experiments.
