Bridge Insight : New Development in Long Span Arch Bridges
Interaction between soil and the foundation plays a vital role in the adequate assessment of forces and stresses in the superstructure as well as soil. The forces in the deck are highly dependent on the stiffness of the soil. There are many methods with considerable assumptions to assess the soil stiffnesses that can be applied as spring support to the foundation. But in most methods, the spring supports are linear in nature and cannot be accounted for higher strains. So, for heavy structures such as bridges and high-rise buildings, consideration of the soil continuum as plastic material is necessary for the design.
This webinar focus on using a Direct Method wherein the soil continuum is modeled in midas FEA NX along with the superstructure (bridge) imported from midas Civil. A plastic material that represents the soil’s behavior will be considered to run an analysis. The force-displacement curves at various locations of the foundation will be taken into midas Civil where they serve as non-linear springs.
1. Interoperability between two software, midas Civil and midas FEA NX
2. midas Civil model data such as node, element properties, boundaries, loads, and analysis control data can be transferred to midas FEA NX
3. Advanced options such as line element geometry from midas Civil can directly be imported as solid or plate geometry in midas FEA NX
4. Required Load Combination Reactions from midas Civil can easily be exported as Loads in midas FEA NX
5. Springs Data from midas FEA NX can easily be transferred to midas Civil – Soil-Structure Interaction
