Simulation with Soil and Concrete Models
Foundation and Retaining Wall Analysis in Ansys Mechanical
Select, understand, and apply material models for concrete, reinforced concrete and soils for foundation and retaining wall analysis applications. This training is offered as a 1-day course.
Duration
1 day
Prerequisites
Basic knowledge of Ansys Mechanical
Software used
Ansys Mechanical
- Carrying out working load analyses for reinforced concrete
- Bearing capacity and a settlement analysis with several soil models
- Identifying material parameters and being able to input them correctly
- Mastering efficient control of non-linear computation with several geo-mechanical models
Description
The fields of mechanical and civil engineering are becoming more intertwined due to the increasing complexity of projects in fields such as structural engineering and the energy sector. This higher complexity results in the increasing importance of a realistic description of geo-mechanical materials and concrete in practical applications. To accurately predict both the bearing capacity and soil settlements, a realistic description of geo-mechanical materials and their implementation in Numerical Simulations is needed. Realistic modeling of concrete materials is necessary to optimize the dimensions of concrete foundations or concrete stabilization walls. The actual interaction between concrete and soil must be taken into account for optimal design.
In this course, you will learn how to perform bearing capacity analysis for reinforced concrete and settlement analysis with various soil models. You will recognize material parameters and define them in Ansys Mechanical. Practical exercises enable you to quickly familiarize yourself with foundation modeling. You will acquire the basic knowledge for controlling nonlinear foundation analysis. The training is intended for civil and mechanical engineers working in interdisciplinary teams who want to be able to model the behavior of geo-mechanical materials for product development and construction projects based on realistic computer simulations.
