In this video, we'll explore
In this video, we'll explore how to model beams on elastic ground foundation in Autodesk Robot. We'll cover the basics of creating a structural model in Autodesk Robot, including how to define the properties of the structure and how to apply loads and boundary conditions.
We'll start by discussing the importance of understanding the behavior of beams on elastic ground foundation in the design process and how they can help engineers ensure the stability and safety of structures. We'll then dive into the specifics of creating a structural model for a simplified structure, including how to define the properties of the structure, how to apply loads and boundary conditions, and how to create different sections of the structure.
Next, we'll provide step-by-step instructions and helpful tips for modeling beams on elastic ground foundation in the model. We'll cover the basics of defining the foundation, including how to specify the soil properties, how to create the foundation elements, and how to apply the loads and boundary conditions. We'll also cover the basics of modeling the beams, including how to define the beam properties, how to create the nodes and members, and how to apply the loads and boundary conditions.
Finally, we'll discuss the importance of interpreting the results of the analysis and how they can be used to improve the design of the structure. We'll provide practical tips and guidelines for designing structures using beams on elastic ground foundation in Autodesk Robot.
Whether you're a student, a practicing engineer, or simply interested in the behavior of structures, this video will provide you with valuable insights into modeling beams on elastic ground foundation in Autodesk Robot using a step-by-step tutorial.
Hi there, CEE Editor Here,
a small hint about the video (Beams on Elastic Ground).
Please note that the implementation in this video is different than what you would have in a "tie beam spread footing configuration"
And here is the thing:
In a spread footing + tie beam configuration, the spread footings would be responsible of carrying the loads of the columns, whereas the tie beams are only responsible for loads above them and also help in resisting differential settlement or horizontal movements of the column bases.
There reinforcements is kind of typical. Between 2-3 ø12-16 top and bottom. With stirrups around ø8/100-150mm
The beams in the video are different, those are fully responsible for carrying the 1 story structure. Now please note that the structure was a 1 story structure, so its loads are kind of small.
In reality, having beams only to carry a multi-story structure is not a good idea. Even for the single story, I added rafts at the end of the video.
I will tell the recorder guy to be doing another video about elastic foundations for beams next time, that gives some more basics and shows an application in the "spread footing + tie beam" sense.
Regards,
CEE Editor.
Current Video Ideas for the Future:
- Influence Surfaces
- More details about modal participation / report?
- Masses and stiffnesses to control modes
- LL Reduction in ACI/ASCE (vertical and horizontal)
- A possible way to model columns with pressure areas
- Deeper dive into slab reinforcement.
- Raft with larger thickness and positions
- Robot - seemingly - erratic deformation when supported by beams and columns
- A way to manually “clean-up” simple mesh like the above
- Wood and Armer Moments in Slabs and their meaning
- Complex and Principle results
- Simple TBM tunnel lining analysis in robot
