RAM Concept Help

Drawing shrinkage area loads

You use the Area Shrinkage Load tool () to locate the area vertices.

While it is neater to draw area loads that match the floor, it is satisfactory to make the area oversize. RAM Concept ignores any part of an area load that is not on a floor element. Exaggerating the size too much affects the automatic printing and zooming bounds.

For multi-story structures, it is recommended to input the shrinkage strain that represents the relative shrinkage change between the level being analyzed and the restrained level below. Using a total shrinkage instead of a differential shrinkage will normally be overly conservative.

  1. Select the Area Shrinkage Load tool.

  2. Either:

    Click at the vertices of the area load

    or

    Enter the coordinates in the command line

  3. Close the polygon by either:

    Click the first vertex

    or

    Type <c> in the command line
