There is similar input for hold-downs at two places in the program – the Wall Input form and Opening Input form. In each place, a hold-down data group contains the following input fields: The input of these data applies to all selected walls.
Hold-down drop-list
For both left and right ends, used to select the hold-down to be used from the list in the database.
Single- or double-bracket
A check box indicates that the hold-down is double bracket, that is, the displacement and maximum anchor bolt length entered in the hold-down database applies to only one-half of the assembly, and is doubled for the hold-down assembly used.
Apply to Openings
When this is checked, the inputs apply to all openings on the wall as well as the wall end studs, saving you the effort of updating all the openings manually.
