| Properties | Description |
|---|---|
| Label | Name of a thickness. |
| Color | Color for displaying a thickness |
| Direction X | Click this button to open the dialog where you can define the main orthotropy direction. |
| List of types of predefined geometry of surface elements | Expand the list and select a predefined geometry of a surface element. To define a custom stiffness, select user-defined from this list. Then click Define and specify the geometry by defining membrane, flexure, and shear stiffness matrixes. |
| Geometrical parameters | Contains edits fields where you define parameters of the predefined floor geometry. It is updated after you select a floor geometry to display parameters appropriate for your selection. |
| Disregard stiffness of transverse bending | Available when you select the predefined geometry: hollow slab.
Select the check box to ignore the bending stiffness K_YYYY in analysis. Do it to enhance modeling of the precast hollow slabs. Deselect the check box to include the bending stiffness K_YYYY in analysis. |
| Coefficients | Available when you select the predefined geometry: constant thickness with reduced stiffness. Click Coefficients to open the Coefficients of Stiffness, Weight, Mass dialog. There you can specify coefficients of reduction of the matrix elements: membrane stiffness D, flexure stiffness K, and shear stiffness H. |
| Display or Define | The Define button displays after you select user-defined on the list of types of predefined floor geometry. Otherwise, the Display button displays. Click the button to open the Stiffness Matrices - Orthotropy dialog. |
| Thicknesses | Select this option to edit the Th, Th1, and Th2 values. They are calculated automatically based on the geometry of a surface element. If you select a user-defined geometry type, Thicknesses is selected automatically. |
| Th | The equivalent thickness used to calculate the self-weight of a surface element. |
| Th 1 | Use it to specify the equivalent thicknesses for analysis when applying thermal gradient loads. |
| Th 2 | Used it to specify the equivalent thicknesses for analysis when applying thermal gradient loads. |
| Parameters of foundation elasticity | Click this button to open the Definition - Elastic Foundation dialog. There you can define the Kz elastic foundation coefficient. |
| Material | Material assigned to the thickness. |
