2D Plate modelling
(OP)
hello friends,
i have a question, i have to do 2d plate analysis for contineous beam, for which i am looking for following information, 1) could any one suggest me good reading material regarding 2d plates? more specifically for beams if possible, 2) does the third dimension in case of beam 2d plate modelling have to be till certain thickness and not what is the actuall thickness of beam? as to fulfill 2D Plate requirements, i.e in my case my beam is 250mmx500mm so when i am doing 2d plate do i need to keep thickness 250mm or 250/10, as i read something but dont know the reason, 3) last but not least, if in case of keeping the thickness as 250/10 then do i need to apply the same load as to be applied to the whole thickness or do u need to divide the applied load as well by Load/10?
THanks

RE: 2D Plate modelling
If it's a beam, why do you have to do a 2D plate analysis? Beams are analyzed as lines, not plates. For continuous beams, you go to your big structural book, look it up, run the numbers and you're home free. Or if the spans aren't even, you might run STAAD, or horrors, slope deflection or moment distribution.
Do you have a supervisor? I think you're making a big deal over an easy problem.

I confess I exclusively use Risa for all my plates. Remember to make the plates small for accuracy.

You cannot model beams as a 2D plate element attached to other slab plate elements (if you mean basic plate elements that most people use for flat plate analysis.). A shallow beam thickening may be ok but not a real beam. Thin Plate elements have no real concept of depth and the stress conditions where they attach where there are large depth differences would be completely stuffed as I understand it.
