-Slab-on-Grade DESIGN PROCESS

(a) DWG file imported into ADAPT-SOG.

(b) Imported drawing is converted into structural components.

(c) Post-tensioning tendons are generated.

(d) Loads are applied on the structure and soil properties specified.

(e) Finite Element mesh is generated.

(f) Design Strips are generated in two orthogonal directions.

(b) EDGE LIFT

(g) The file is broken into two separate models to represent both edge lift and center lift conditions.

(h) Deflection contours from Finite Element Method (FEM) demonstrate the response of structure for both swell modes.

Allowable Stresses

Calculated Stress

(i) Design Sections are generated automatically for stress check. Locations, where stresses do not meet the allowable values, are shown in red (broken line).

(j) Calculated bending and shear stresses for each Design Strip can be superimposed on the allowable stress envelope.

(k) Structural drawings can be either printed directly from the program or exported to AutoCAD.
