1 All values are for anchor installed in hollow core concrete with minimum compressive strength of 7,000 psi . Due to variations in materials and dimensional configurations , on-site testing is required to determine the actual performance of the anchor . Allowable loads are calculated using a safety factor of 5 .
2 Tabulated embedment depth is limited by the plastic HIT-SC 16x50 mm screens . See Figure 12 .
3 The required concrete thickness is the thickness for which values are available and installation is recommended . Anchors shall be installed along the centerline of the hollow core or along the line of minimum thickness . Verify these requirements with the hollow core plank supplier before installation . The required thickness is measured from the inner to the outer side of hollow core panel . See Figure 12 .
4 Tabulated allowable loads must be the lesser of the adjusted bond values tabulated and the steel values in table 3 . 5 Allowable loads shall be adjusted for increased base material temperature in accordance with Figure 13 . 6 For combined loading : ( T applied
/ T allowable ) + ( V applied
/ V allowable ) ≤ 1

1 Representation of the tested conditions for which allowable adhesive bond loads are applicable . Refer to footnote 3 of corresponding load table above for more information on requirements and restrictions on the admissible anchor installation .
2 Minimum edge distance is 6-inches . Minimum spacing is :
- 8-inches along the length of each hollow core section .
- One anchor per hollow core section ( left and right on page ), 6-inches minimum between adjacent hollow core sections .
