What is Design Thickness?

Design thickness is a term used in structural engineering to refer to the thickness of a structural element (such as a beam, column, or plate) that has been calculated or specified based on the design requirements of the structure. The design thickness is the thickness that has been calculated or specified based on the structural requirements of the beam and the strength and deformability of the soil or foundation on which the beam will be supported. The design thickness of a bottom plate is typically determined by a structural engineer or using structural engineering software, and is used to ensure that the bottom plate is able to safely carry the loads that will be applied to it during the life of the structure.
