Used to change the element thickness for the plate elements in a mesh you are using to model a mat foundation.

As slab is added as a physical entity in STAAD Foundation Advanced, default slab thickness property will be automatically created and assigned to each slab region.

Opens when Mat Foundation Job > Analysis Properties > Slab Thickness is selected.

The first row of the table is to select unit for thickness. You can have only one unit for all slab thickness.

Second row onwards will be list of slab thickness properties. Left most cells of each row will show the region identifier name as specified in Meshing Setup operation.

STAAD Foundation Advanced allows you to use different thickness for analysis and design. Analysis thickness will be used for FEM analysis of mat foundation and design thickness will be used to design the mat slab. This is particularly important in modeling a pedestal, where you may want to use excess thickness for stiffness modeling but want to use slab thickness for design.
