## Function

- You can input or modify the degree of freedom constraint data of arbitrary nodes in a Spreadsheet format table using midas Civil's Table Tool.

## Call

From the main menu, select **[Boundary] tab > [Tables] group > [Boundary Tables] > [Point Spring Supports]**

## Input

(refer to "Point Spring Supports")

Please refer to the documentation or user guide for the Table Tool to learn how to input or modify the following data.

**SDy** : Spring stiffness in GCS Y-direction (Node's local y-axis direction)

**SDz** : Spring stiffness in GCS Z-direction (Node's local z-axis direction)

**SRx** : Rotational spring stiffness about GCS X-axis (Node's local x-axis)

**SRy** : Rotational spring stiffness about GCS Y-axis (Node's local y-axis)

**SRz** : Rotational spring stiffness about GCS Z-axis (Node's local z-axis)

**Damping** : Damping constant

**Cx** : Damping constant in GCS X-direction (Node's local x-axis direction)

**Stiffness** : The stiffness of tension-only/compression-only spring

**Direction** : Node local axis direction in which a spring is assigned

**X** : X direction component of a vector which accounts for the direction of a spring

**Y** : Y direction component of a vector which accounts for the direction of a spring

**Z** : Z direction component of a vector which accounts for the direction of a spring

**Force-Deformation Function** : Function name in which the hysteresis characteristics of multi-linear hysteresis stiffness are defined.

**Group** : Boundary Group in which the entered boundary conditions are included
