Are Hardy Frame® Panels installed on concrete or on a mudsill?
Hardy Frame® products are typically built to a standard wood stud height in California (nominal 8’ = 92-1/4″ net). This net height facilitates installation between a mudsill at the bottom and double top plates above. For designs governed by seismic, the 12″ wide Panels and the 18″ wide with 1-1/8″ diameter hold down bolts, have a decrease in the allowable shear value if they are placed on a mudsill. The amount of the decrease can be determined by comparing the values published in Table 1.1 with those in Table 1.2. In order for these two Panel types not to have a decrease in allowable shear value, they should be installed either directly on the concrete or per our “double nut” detail.
