midas GSD-Solving for Section Property

Question:

Good Day,

Please see the attached pictures. I am having this error when I use the midas GSD for the computation of the section property of the SRC section as shown. I imported autocad dxf file to GSD and also used the section database in the Midas Civil program for checking. Can you please tell me what is the correct procedure in using the "Import Autocad dxf..." command in Midas GSD?

Many thanks,
Noel

Hello Noel,

Sorry, we couldn't get back to you sooner.
Actually, this is a limitation in GSD.  One shape can have only 1 material property.  Also, the material shapes can't overlap.  Now, kindly refer to the image below.
First is outer shaper, i.e., 0.3m x 0.3m square.  Now, since material properties (and hence, shapes) can't overlap, we have to create a circular hollow region, which would be shape 2.  Then, shape 3 would be the steel pipe.  And to generate the section as required, there would have to be an inner circular shape with concrete material, which isn't possible.  This limitation can also be understood very quicly by simply trying to import the element from civil to GSD.  The section taken into GSD would be as below.
I hope this clarifies the doubt.  Kindly let us know if further assistance would be required.
