Do Staad.pro Can Analyze Structure with Flat Slab?

Sure, people design flat concrete slabs with STAAD.pro all the time. If you're looking for something more than confirmation just reply with some further details.

You can model slabs of different thickness in STAAD.pro and still export the model for final design to Ram Concept, but if it were my model I would probably just use a single thickness simple slab in STAAD which is probably good-enough for lateral analysis and column design and then export the levels to Ram Concept where you can add the drop caps, tendons, design strips and punching checks.

Now, I personally think that the integration of RAM Structural System with Concept is a little tighter than the link between STAAD and Ram Concept, so if you already have the model in RAM SS you could continue with that. Since the program does not generate Wind or Seismic loads per the Indian codes yet you would have to put in use defined lateral loads. The biggest limitation I see is in the concrete column design within RAM SS which has a lot of concrete design codes, but not the Indian Standard.

Hi sir,

Hi, I realize that, if I model flat slab with plate element and use pinned support at the column location, it will induce high localized shear stress, especially at the edge. Do I need to include dummy elements to resolve such issue? The structure do not have beams.

I am actually modelling a slab supporting on piles and I think this should be similar to flat slab supporting on columns. The following shows the loading conditions and the results of out of plane shear. 

I also include my model here.Launch chamber.STD
