Point Spring Supports Table
Enter or modify point spring stiffness data for each GCS direction in a spreadsheet format Table.
Table Tool in midas Civil offers a variety of powerful built-in functions. Refer to the following items for detail directions:
Basic directions (Cell motion, selection, size control, etc.)
Data manipulation (Add, delete, modify data, etc.)

Refer to Usage of Table Tool and enter or modify the following data:
.jpg)
Node: Node number
Type: Type of springs (Linear / Compression-only / Tension-only / Multi-Linear)
SDx: Spring stiffness in GCS X-direction (Node's local x-axis direction)
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)
Stiffness: The stiffness of tension-only/compression-only spring in ECS x-direction
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
Multi-Linear Type: When multi-linear hysteresis stiffness is selected, select whether the tension and compression stiffness is symmetric or unsymmetric.
ax/ay ~ fx/fy: Directly enter the hysteresis characteristics of multi-linear hysteresis stiffness.
Group: Boundary Group in which the entered boundary conditions are included
