3D FE analysis of bespoke steel connection

[O.Maille]

I need to design a bolted flange to flange connection for a railway beam.

I can model the beams and bolts in Acad, 3ds max, blender etc....

I have the infrastructural and building design suites.

Can I import 3D solids into robot?

if not I can created surfaces and mesh solids...what is the best way?

Yes , as Solids. IN case of your file just convert surfaces to solids.

Can I import 3D solids into robot?

Yes, this way:

- save solids from ACAD,..., as ACIS solids -> *.sat file

- start Robot with Volumetric structure type

- enable ACIS (see below)

- set proper unit (in case of this file mm)

- open sat file

if not I can created surfaces and mesh solids...what is the best way?

Two other approaches:

1. Model it from scratch in Robot as solids

2. Simplify model (as shell) creating each beam from 3 panels (web + 2 flanges), bolts as ordinary bars

Hi,

I'm trying to import a .sat file (see below), doesn't work, the Solid Modeler options are not available.

thanks

I am unable to open this file neither in Robot nor in Revit  nor in ACAD.

the .sat file was created under Cadwork.

Please have a look on the pdf, maybe I have to choose another ACIS version (21.0, 20.2, ...)?

thanks

It is not possible to select ACIS version in ACAD, RST, Robot.

Try to save sat file in ACIS 13 or 14 or....  format them try to open in our soft.
