Truss Bridge Structure
Description of the deterministic FE model
This tutorial shows how to train a mode-based meta model and compares the results of the meta-model with reference solutions.
The structure of interest consists of truss elements (see figure below).
Definition of the probabilistic model
The probabilistic model used in this tutorial is summmarized in the following table:
Summary of the Probabilistic Model
|Distribution||Mean Value||CoV Value|
| Stiffness of the truss
| Mass of the truss
An excitation is imposed on the node #48 of the structure. The comparison between the FRF of the meta-model and of the full model are shown in the following figures for validation samples.
