Here are a few links that would give you basic information, to start with the design of steel deck slabs: 1. Composite Steel Floor Deck - Slabs - Steel Deck Institute (http://www.sdi.org/wp-content/uploads/2013/04/SDI_ANSI_C_2011.pdf) 2. COMPOSITE SLABS AND BEAMS USING STEEL DECKING-Best Practice Guide-SCI Publication P300 ( http://smdltd.co.uk/wp-content/uploads/2013/02/SCI-Publication-P300-MCRMA-TP-No.-013-Best-Practice-Guide-REVISED-EDITION.pdf) 3. Composite Deck Catalog - ASC Steel Deck (http://www.ascsd.com/files/floordeck.pdf) 4. Metal Decking Design Guide - New Millennium Building Systems (http://www.newmill.com/pdfs/DeckDesignGuide.pdf) 5. Design of composite steel deck floors for fire (http://www.steelconstruction.info/Design_of_composite_steel_deck_floors_for_fire) If I remember correctly, there is a design example in composite floor design chapter of steel design textbook by McCormac, for calculating number and sizes of shear studs as well. Regards.

Muneeb, These elements are part of diaphargm design.. Collectors are drag stuts (not always required). Anyway, if you have any topic up your sleeve, we can write about it. If not then lets detail an article about diaphragm design.. Send me an inbox about whatever suits you.. Thanks.

Dear Umar, What do you mean by Chord and Collector Elements. Is it from diaphragm design. If so then why only chord because in diaphragm, there are many other type of reinforcements. Anyways I am interested in anything in which I can contribute. Thanks Muneeb

Apart from what Uzair has suggested, I would also recommend you the software for metal deck design. It is COMDEK by Tata Steel. Update: I think they have changed it to "ComFlor" and the link is here http://www.tatasteelconstruction.com/en/about-us/building-envelope-and-structural-decking/technical-information/comflor/software

Yes, that is basics 101..

Dear Hafiz Athar Farooq, Just send me the plan and your requirements. No. of stories required and usage requirements. I ll design it for you for free Thanks Muneeb

They are doing it right. It depends on you. It is the beauty of the structures that they will behave the way you designed them. When reducing the torsion modifier for beams that are failing to a value approx equal to 0 then watch for the increased moments in slabs. If you put the reinforcement in slab for additional moment then it is ok! It depends upon the relative stiffness of beam and slab that how much load beam will take (Torsion, moment etc).
