{{Main|Plate (structure)}}

Plates carry bending in two directions. A concrete flat slab is an example of a plate. PlatesPlate arebehavior understoodis bybased usingon [[continuum mechanics]], but. dueDue to the complexity involved they are most often designedanalyzed using a codifiedfinite empirical approach, or computerelement analysis.

They can also be designed with yield line theory, where an assumed collapse mechanism is analyzed to give an upper bound on the collapse load. This technique is used in practice<ref>{{cite web |title=Assessment of a Pair of Reinforced Concrete Roof Slabs |url=http://www.ramsay-maunder.co.uk/downloads/precast_roof_slabs.pdf |website=Ramsay-Maunder.co.uk |publisher=Ramsay Maunder Associates |date=2011 |access-date=2022-03-08 }}</ref> but because the method provides an upper-bound (i.e. an unsafe prediction of the collapse load) for poorly conceived collapse mechanisms, great care is needed to ensure that the assumed collapse mechanism is realistic.<ref>{{cite web |url=http://www.ramsay-maunder.co.uk/downloads/l_shaped_landing.pdf |title=Reappraisal of a Simply Supported Landing Slab |website=Ramsay-Maunder.co.uk |publisher=Ramsay Maunder Associates |url-status=live |archive-url=https://web.archive.org/web/20160304071038/http://www.ramsay-maunder.co.uk/downloads/l_shaped_landing.pdf |date=2011 |archive-date=2016-03-04 |access-date=2022-03-08 }}</ref>
