the left column of the table. To assure the stringer is properly supported read right to the stringer material
column. This intersection is the OC spacing of the shore. Maximum shore spacing is also dependent on shore
strength and end bearing of the shore on the stringer.
Use the allowable load from Table 3-7 and Table 3-8 on page 3-22, based on the shore strength and the bearing
stress strength of the stringer.
NOTE: Unsupported length = height above sill--sheathing thickness--joist thickness--stringer thickness. This
length is then rounded up to the next higher table value.
