design of metal deck
i am new on this forum. presently i am working on design on metal decks. can anybody suggest me general guidelines for the use of metal deck?
thanks

check out our whitepaper library.
one of over 353,000 possible answers from google:
google it, then pick vulcraft, canam, etc and use their load charts. also the sdi has a design manual. is this for a slab, or roof, if roof, you need to check for diapham action of the deck if its the lateral system
go to
check out sdi.org website.
i cannot believe that any design engineer who is taking responsibility for a design would blindly accept design charts produced by a manufacturer to justify a design.
find out the design method for the decking you are using from the manufacturer and do the design calculations yourself. if they do not have a detailed design methodology, go to someone else for your decking.
if the deck manufacturer is a member of the steel deck institute their load tables have already been reviewed by the institute. if you want to recreate the wheel go ahead. i have been using these tables for over 30 years and have never found any problems with any

have you discussed this with your insurance company? does the sdi or the manufacturer explicitly take responsibility for the design, or is there the usual fine print stating that the final responsibility is yours?
rapt....what you are referring to is called "specific reliance". engineers routinely rely on tabulated values from reputable sources. to rely on such does not violate the standard of care.
while it is prudent to evaluate the methodology from which the companies derive their values on a spot-check or documentative quality assurance effort (much the same that you would do for validating analytical software), it is not necessary to hand calculate each condition. continuing with the software analogy, if you did this with software, it would defeat the purpose of having and using the software.
rapt-
do yo go to aci every time you use a hilti anchor? do you go to the nds every time you use a simpson hanger?
if you look closely, even aci and aisc relieve themselves of liability.

ron,
so you should mahke sure that the design philosophy being used to develop the tables is correct and check some random cases to make sure it has all been done properly and you are happy with the results in the table! then you can use the table for a range of cases. as you would/should do with design software.
i will bet that 99% of consultants do neither of the above, for software or design tables! they simply blindly believe the salesman who produced the tables.
