1 Hilti SLC spacings less than those tabulated may be used . The tabulated spacing should be used in the calculation of diaphragm shear strength when using the Q f
, Q s and c values from Table 8 . Alternatively , only when the SLC spacings are less than those tabulated , the Q f , Q s and c values found in Table 8 can be replaced by the following values .
X-HSN 24 – All deck types , strengths and base steel thicknesses listed in Table 8 22 Gauge ( 0.0295 in .) - Q f
= 1489 lb , Q s = 716 lb , c = 1.000
20 Gauge ( 0.0358 in .) - Q f = 1795 lb , Q s
= 869 lb , c = 1.000
18 Gauge ( 0.0474 in .) - Q f = 2348 lb , Q s
= 1151 lb , c = 1.000
16 Gauge ( 0.0598 in .) - Q f = 2924 lb , Q s
= 1452 lb , c = 1.000
2 For 36 / 9 and 36 / 11 patterns , when wind ( or seismic ) diaphragm shear capacities exceed the values shown below , the fastening pattern must be increased at the building perimeter , chords , collectors or other shear transfer elements to two fasteners per rib ( i . e . 36 / 14 pattern ). The wind ( or seismic ) diaphragm shear capacity must not be greater than that determined from the 36 / 9 and 36 / 11 patterns , as applicable .
