RAM Concept Help

Using RAM Concept 's results to specify stud shear reinforcement (SSR) systems

Typical values specified for an SSR System include number and arrangement of rails at the column or support, first stud spacing, typical stud spacing, stud diameter, and rail height in addition to the typical stud properties.

Most of the properties required to specify an SSR System are available by plotting the SSR under visible objects > Punch Checks. The overall height of the rails is not reported by RAM Concept but can be easily determined from the geometry. Generally, the height of the rails should be dimensioned to be as close as possible to the structural member's outer surfaces (while observing necessary cover and other Code requirements). RAM Concept 's strength calculations assume that each individual shear stud rail has a single effective depth, calculated as the thinnest effective depth of any slab area intersected by the shear stud rail. A punching design may have shear stud rails with multiple depths at a column or support.

For the Ancon Shearfix system design, the input covers are used to calculate a physical rail depth and used to generate the Ancon part numbers shown in the punching report.
