Line spring properties

The following is a list of RAM Concept line spring properties:

Elevation above slab soffit Vertical distance between the line spring and the soffit.

Spring Angle (R=X, S=Y@0) Orientation of the local axes. The plan shows spring orientation.

R-Force Constant Spring constant in the direction of the local r-axis at each end.

S-Force Constant Spring constant in the direction of the local s-axis at each end.

Z-Force Constant Spring constant in the direction of the global z-axis at each end.

R-Moment Constant Angular spring constant about the local r-axis at each end.

S-Moment Constant Angular spring constant about the local s-axis at each end.

Note: If the force constant (or moment constant) is uniform you need to enter only one value. Otherwise you need to enter two values separated by a comma (ends 1 and 2). This allows linear variation of the force constant (or moment constant).
