Do Staad.pro Can Analyze Structure with Flat Slab?

Hi everyone can somebody already design Structure with flat slab in Staad.pro?

Thanks

    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.

    Hello,

    Dear Sir, I have to design a G+8+1SF office building with post-tensioned slab without using beams. I know that I can design slab using RAM concept. I know that I will require some drop caps or column caps to counter punching shear effect. But how to model those here in staad.

    2. I first thought to move my entire model in RAM Structural system and waste almost an entire day for training at bentley institute to alternatively found out that RAM Structural system does not support any indian or south african code.

    Please I do require some guidance.

    Thanks and Regards

    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.

    Thank you so much Sir.

    I want to confirm something that while modelling flat slab using plates in staad, the necessary points are
    1. proper meshing of plates
    2. master slave definition for the whole floor to define the rigid link between slab and columns.

    is that correct?

    Thanks and Regards

    Meshing the slab is important as you said. However please note that if you are modeling the floor using plates having appropriate thickness, you are already accounting for the stiffness due to the flat slab and so you do not need to define master slave on top of it. At column locations where there are caps, you can add a few dummy beams ( use high E and zero density for these ) connecting the column point to the adjacent nodes of the plate mesh. That would simulate a stiff cap and help distribute the stresses.
