Defining composite section for end PSC girders

Question:

Hi,
How do we define a  composite section (prestressed concrete I girder and concrete slab) in MiDAS Civil with unequal slab widths on either side of girder centerline? I am trying to define composite section for end girders that have unequal flange widths of slab.

Thanks,

Hello,

For this purpose, the Section Property Calculator (SPC) would have to be used.  You can either import a dxf drawing file with such unsymmetric section to SPC or directly generate the geometry in SPC.
A tutorial on how SPC could be used is attached.  Kindly let us know if further assistance would be required.

Hi Nandeep,
We do not use AutoCAD here in our office. So creating/exporting dxf file is not an option. Is it possible to skip the step of importing dxf file by drawing the geometry in the SPC itself? Then this geometry can be used in subsequent steps.

Thanks,



I forgot to mention that we also have MiDAS FEA that we use here. Let me know if there is any way in which the geometry can be sketched and exported from FEA and then imported to Civil.




Hello,

The geometry could directly be generated in SPC itself.  The tools for that are quite intuitive.
Kindly let us know if further assistance would be required.

Hi,
I have midas civil 2016 (v2.2) on my system [see attached screenshot]. If i need to import a dxf file is there a limit on the highest year of dxf file that is compatible with this version. I generated a dxf file with microstation but when i imported into SPC i could see only random lines and points. I am attaching the dxf file as well.

Thanks,



Hello,

It was noted that drawing file had polylines.  Only lines could be imported.  Hence, the ploylines were changed to lines and the geometries were imported.  The SPC file is attached for your reference.  Kindly let us know if further assistance would be required.
