In elastic theory, a plate is a structural element whose thickness is small compared to its other dimensions (length and width). When a plate is loaded perpendicular to its plane (out-of-plane loading), it bends. Slabs are essentially concrete plates, while diaphragms are plates loaded in their own plane (in-plane loading), typically to transfer lateral forces from wind or earthquakes. When a slab has a free edge or

Design codes (such as Eurocode 2 or ACI 318) provide simplified methods (like the "coefficients method" for one-way or two-way slabs), but they come with limitations regarding edge conditions. When a slab has a free edge or is supported by a stiff beam on one side and a wall on the other, standard code coefficients may be insufficient. Bares’ tables provide precise coefficients for these "non-standard" boundary conditions, ensuring an accurate elastic analysis that prevents over-design (waste of concrete) or under-design (risk of failure).

Coefficients are provided based on the ratio of the long side ( ) to the short side (
