Hold-down Design

Hold-down Location

The program performs the design check for hold-down capacity at each wall or opening end.

Vertical elements

There is currently no mechanism for entering hold-downs at the base of vertical elements transferring a force from an upper storey via a vertical element to a location on a lower story that is not a wall or opening end on that story. so is no hold-down design for those hold-down locations.

Anchorages

The program does not perform the design check at hold-down locations where there are anchorages.

Design Check

For each design case (wind, seismic, and both force directions), the program checks the capacity of the hold-downs at each hold-down location against the combined factored uplift force. The combined force includes:

• shear overturning
• counteracting dead load
• wind uplift

  Design Method

This is a design check only on a hold-down selected for the hold-down location. The program does not at this time cycle through various possibilities to find a hold-down.
