How to properly model framing plan in ETABS?

How to properly model framing plan in ETABS?

How to properly model framing plan in ETABS?

Hi! I'm new to the software. How do I model a frame in ETABS? Should I model it using centerline? What if in the architectural plan the perimeter beams is flushed to one side of column?

Thank you all!

RE: How to properly model framing plan in ETABS?

I will try to answer (with my limited experience)...

Best practice is to use gridlines to accurately input the column positions.
This accuracy will also help later if you want to do a architectural overlay for cross-checking.
It is also good for setting up gridline elevations later which you can use to easily view bending moments, shear forces etc. along a certain section of the structure.

Columns, beams, walls, slabs, etc. are all modelled based on their centerline positions. If needed, you can apply centerline offsets later on inside the properties for specific members.

Your example of the perimeter beams is one where I would probably ignore offsetting the beam to match the architectural drawings. I think the effect of the offset on the loading mechanisms/transfer to the column may be quite small/negligible... but I could be wrong here. Would welcome the input of others!

White Paper - How ESI is Helping Move New Medical Device Product to Market Quicker & More Cost Effic
Early Supplier Involvement has long been a strategy employed by manufacturers to produce innovative products. Now, it almost seems like a necessity. Because decisions made in the design phase can positively affect product quality and costs, this can help add value to OEM bottom lines. This white paper will discuss many facets of ESI, including why it’s so valuable today, what challenges limit the benefits of ESI, how cost is impacted, and more. Download Now
White Paper - Moving to a Driverless Future
This white paper describes what we see as the best practices to support a sustainable engineering process for autonomous vehicle design. It exposes how to use simulation and testing in common frameworks to enable design exploration, verification and validation for the development of autonomous cars at a system, software and full-vehicle level to drive a mature product development process for automated driving.
