Line load properties

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

SettingDescription
Name User-defined label used to identify the line load in output.
Elevation above slab surface Vertical distance between the line load and the slab surface.
Fx Line force in the direction of global x-axis (horizontal force).
Fy Line force in the direction of global y-axis at each end (horizontal force).
Fz Line force in the direction of global z-axis at each end (vertical force).
Mx Line moment about the global x-axis at each end.
My Line moment about the global y-axis at each end.
Notes:
  • If the line force (or moment) 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 line force (or moment). See the following figure.
  • Although line loads need not be located at a finite element node, you should consider locating very large loads at element edges. Line loads must be completely located on finite elements; RAM Concept issues a warning if you violate this rule.
  • Sign convention is defined in Criteria > Signs. See Choosing Sign Convention .
  • Horizontal forces (Fx, Fy) cause applied moments unless the Elevation above slab surface is set to apply the load at the slab centroid.

Line load properties varying from 10 to 20 units.
